System firmware changes that affect all systems

A problem was fixed for a system HMI that can occur if a GPU Address Translation Request (ATR) exceeds the time out period.  With the fix, the timeout period was extended to allow worst case extra time for memory accesses if the data was not in the cache.

A problem was fixed for SRC BC70E540 being logged during memory diagnostics in the IPL with no hardware FRU being called out for replacement.  This SRC has description "mcb(n0p0c1) (MCBISTFIR[12]) WAT_DEBUG_ATTN".  This is a false error log and it may be ignored.

System firmware changes that affect all systems

A problem was fixed for a rare IPL failure with SRCs BC8A090F and BC702214 logged caused by an overflow of VPD repair data for the processor cores.  A re-IPL of the system should recover from this problem.

A problem was fixed for a rare IPL failure with one of the following symptoms:

1) An eSEL is logged stating an IPMI timeout occurred.

2) A Hostboot timeout error occurs with a message like "Unrecoverable Hardware Failure, (Critical) Hostboot procedure callout.".

3) An eSEL is logged:  "FQPSPCR0023M | <timestamp> | Yes | Critical | Hostboot has become unresponsive | None".  

A re-IPL of the system should recover from this problem.  The IBM Knowledge Center document on this problem is titled " FQPSPCR0023M" and can be found at the following link:  https://www.ibm.com/support/knowledgecenter/en/POWER9/p9ia7/FQPSPCR0023M.htm

A problem was fixed for failed FRUs associated with checkstops in hostboot not being guarded.  This is an intermittent timing problem related to error log entries that have been created but not written or flushed yet at the time of the guard processing.

A problem was fixed for handling On-Chip Controller (OCC) UE errors so that the OCC can reset without terminating the system.  Without the fix, the system will checkstop on any OCC UE that requires a reset of the OCC.  A re-IPL of the system will recover from this error.

A problem was fixed for an IPL failure caused by an IPMI timeout.  This is a rare problem and the re-IPL after the failure recovers from the problem.  The eSEL for the IPMI timeout may be ignored.

A problem was fixed for intermittent recoverable errors on the LPC (Low Pin Count) bus being falsely shown as Unrecoverable Errors (UEs).  This can occur for some recoverable errors that happen when writing to the serial console.  Even though the recovery works, the status for the recovery is misread, causing it to be shown as unrecoverable.

A problem was fixed for a Linux host crash caused by a CPU hard lockup.  This can occur when the BMC is rebooted and the normal unresponsiveness of the BMC during this reboot time triggers a time-out on the Pervasive Interconnect Bus (PIB) and a subsequent CPU lockup.  With the fix, the host code will do PIB resets and retries until the BMC has completed its reboot and is responsive again to commands.

A problem was fixed for a GPU being reset from an error state remaining fenced and not usable.

A problem was fixed to prevent printing a null when parsing and formatting VPD data.

A problem was fixed for a hang in the OS reboot caused by a TOD failure.

A problem was fixed to increase the severity of abnormal reboot events in the error log.

A problem was fixed in IPMI for a case where a pointer continued to be used after it was freed, causing an intermittent fail if the memory was reused.

A problem was fixed for eSEL PANIC logs not always being sent to the BMC before taking the system down with the error, causing the loss of a log.

A problem was fixed for an OS boot that fails because the BMC is going through a reboot itself.  The OS boot can fail when it needs to use BMC services when accessing the flash memory.  This can happen if the BMC is not ready to receive commands.  With the fix, the boot waits for the BMC to become ready instead of failing immediately on the errant flash access.

A problem was fixed for a fast reboot of the OS failing if VFs (Virtual Functions) were enabled and disabled before the reboot.

A change was made to enable OS software checkstops by default.  This prevents hangs of multiple hours in failed reboots if the CPUs become stuck at the start of a kdump.

A problem was fixed for bad flashes caused by data size of memory to flash not being block aligned.  This error can intermittently cause partial data to be written to the flash.

Impact:  Data   Severity:  HIPER

System firmware changes that affect all systems

HIPER/Pervasive:  A problem was fixed where, under certain conditions, a Power Management Reset (PM Reset) event may result in undetected data corruption.  PM Resets occur under various scenarios such as power management mode changes between Dynamic Performance and Maximum Performance, power management controller recovery procedures, or system boot.

A problem was fixed for false processor core failures with SRCs BC131705 and BC8A090F logged.  To recover, reboot the system as these are cores intermittently falsely reporting as failed during the IPL.

A problem was fixed for IPMI power down and power on raw commands failing when issued in IPMI Restriction Mode.  For this error, the host goes unresponsive with the following SEL list and message logged to the BMC gui after the raw commands are issued from ipmitool:

root@powerkvm3-lp1:~# ipmitool -I lanplus -H 9.40.192.54 -P 0penBmc sel list

 195 | 02/05/2019 | 09:48:19 | System Event #0x01 | Undetermined system hardware failure | Asserted

 196 | 02/05/2019 | 10:36:54 | System Event #0x01 | Undetermined system hardware failure | Asserted

 197 | 02/05/2019 | 10:40:53 | System Event #0x01 | Undetermined system hardware failure | Asserted

And the following error logged in the BMC GUI:

FQPSPCR0023M: Hostboot has become unresponsive

 _PID=2868 MESSAGE=org.open_power.Host.Boot.Error.WatchdogTimedOut

A problem was fixed for not being able to change the "IPMI admin" password away from the BMC default.  With the fix, the "IPMI admin" password can be changed using the ipmitool command. Note: The "IPMI admin" password is independent of the "normal admin" password on the BMC, such as that used by the REST APIs.  When REST is used to change the admin password, it is changing the "normal admin" user ID password, not the "IPMI admin" user ID password.  Consider changing both of the "admin" user passwords to provide better security.  The following is an example of using the ipmitool command to change the "IPMI admin" user ID password (The "1" represents userid 1, which corresponds to the " IPMI admin" user):

ipmitool user set password 1 your-new-IPMI-admin-password

Support was added to recognize a port parameter in the URL path for the Preboot eXecution Environment (PXE) in the ethernet adapters.  Without the fix, there could be PXE discovery failures if a port was specified in the URL for the PXE.  

A problem was fixed for a skiboot hang that could occur rarely for a i2C request if the i2c  bus is in error or locked by the On-Chip Controller (OCC).

A problem was fixed for "Unexpected TCE size" error messages when Linux tried the default P9 PHB4 pages size and used the unsupported  2M and 1G page sizes.  The TCE page size property is now set correctly with 4K/64K/16M and 256M supported.

A problem was fixed for PCIe ECC protection in the response data path for Power 9 processor parts.  With the fix,  PCIe ECC errors detected from the adjacent AIB (Adapter Interface Board) receive data path escalate to a checkstop so that the defective parts can be replaced.

A problem was fixed for an intermittent rare processor core lock failure that is not a real hardware problem.  The erroneous failure looks like this in the logs:

LOCK ERROR: Releasing lock we don't hold depth @0x30493d20 (state: 0x0000000000000001)

A problem was fixed for the power-capping range allowed for the user.  Changes were made to allow the user to access the entire powercap range, with two minimums exported into the OS:  soft power cap minimum  "powercap-min" and the hard power cap minimum limit "powercap-hard-min".

A problem was fixed for an OS reboot after a shutdown that intermittently fails after the shutdown.  This can happen if the BMC is not ready to receive commands.  With the fix, the messages to the BMC are validated and retried as needed.  To recover from this error, the system can be rebooted from the BMC interface.

A problem was fixed for a kernel hard lock up that could occur if IPMI synchronous messages were sent from the OS to BMC while the BMC was rebooting.  For these type of messages, a processor thread remains waiting in OPAL until a response is returned from the BMC.

A problem was fixed for a rare Nest Memory Management Unit (NMMU) hang calling out processor hardware incorrectly, masking the real cause of the problem which is an NPU failure.   The incorrect error messages take this form on the system:

3      | FQPSPPU0093G  | 2018-10-01 01:25:40  | Yes          | Warning   | CPU 1 has exceeded a correctable error threshold

4      | FQPSPPU0093G  | 2018-10-01 03:20:55  | Yes          | Warning   | CPU 0 has exceeded a correctable error threshold

5      | FQPSPAA0008M  | 2018-10-01 04:35:40  | Yes          | Critical  | Hostboot procedure callout

A problem was fixed for intermittent user and user level privilege errors for the OS ipmipower command.

The following error message is issued:  " privilege level cannot be obtained for this user".

OP9_v2.0.11_1.8/OP910.30

02/13/19

Impact: Security       Severity:   SPE

New features and functions

Support has been re-enabled for erepair spare lane deployment for fabric and memory buses.  

Support was added for increasing the number of BMC error logs from 100 to 200 and changing the error log to roll over old entries when full instead of stopping the logging of errors.  Without this feature, the error log would get full at 100 entries  and error logging would be stopped until some  of the error logs were purged to make room for new entries.

System firmware changes that affect all systems

A security problem was fixed to prevent a buffer overflow when loading the boot image that could cause firmware corruption.  The firmware mitigation adds additional checking of the initial boot firmware image's load size and terminates the boot if the size is too big.  The Common Vulnerabilities and Exposures issue number is CVE-2018-1992.

 A security problem was fixed to prevent host programs from being able to corrupt the BMC using the internal software bridges between the host and BMC.  The Common Vulnerabilities and Exposures issue number is CVE-2019-6260.

 A security problem was fixed to detect and prevent Self Boot Engine (SBE) SEEPROM corruption.   The Common Vulnerabilities and Exposures issue number is CVE-2018-8931.

 A security problem was fixed to prevent a firmware update causing an unsigned image to be activated.  The Common Vulnerabilities and Exposures issue number is CVE-2018-13787.

 A problem was fixed for an intermittent opal-prd crash that can happen on the host OS.  This is the fault signature:  " opal-prd[2864]: unhandled signal 11 at 0000000000029320 nip 00000 00102012830 lr 0000000102016890 code 1"

 A problem was fixed for a PCI Host Bridge (PHB) configuration write error that caused the incorrect PCIe device to be frozen.  The fault will be attributed to the last device to have a memory-mapped I/O operation (MMIO).  With this fix,  the freeze action for PHB configuration write errors is disabled in order to not impact functional hardware.

 A problem was fixed for diagnostic code trying to read sensor values for PCI Host Bridge (PHB) entries that are unused, which causes debug output to have incorrect values for the unused entries.  With the fix, only the used entries are processed by the diagnostic code.

 A problem was fixed for a IPL loop/hang with a fatal MCE exception log caused by a probe of a failed PCI Host Bridge (PHB) that had been guarded.   This is an infrequent error because it requires a PHB to have previously failed. The exception log has the following format:

Fatal MCE at 000000003006ecd4   .probe_phb4+0x570

 CFAR : 00000000300b98a0

 A problem was fixed for repetitive opening of  BMC web sockets during a BMC boot causing the websocket either being opened but no data sent, or the inability to establish a new connection.

 A problem was fixed for certain system boot failures not propagating to the BMC before the boot firmware shuts down.  Some details of the error log may still appear in the console output trace, but the details will not be available with the BMC queries.  This problem is timing dependent and intermittently possible depending on the timing of the shutdown path.  However, immediate shutdowns exacerbate the problem and increase the chance it can occur.

 A problem was fixed for an intermittent error message when activating firmware during a firmware update.  This extraneous error message occurred with moderate frequency.  This is internal server 500 error message returned on the REST enumerate request.  The error message can be ignored as there is not a problem with the firmware activate.

 A problem was fixed for an On-Chip Controller (OCC) read failure with ERRNO=19 during a power off of the system.  This intermittent problem is an extraneous errror log  and can be ignored.as the power off is successful.

 A problem was fixed for an intermittent power on failure with message "Error in mapper call to get service name".  To recover from this problem. power cycle the BMC and try the boot again.   

 A problem was fixed for not being able to set the Power Supply Redundancy by using a REST API command.  Without the fix, this was a read-only attribute.

A problem was fixed for a re-IPL failure of OPAL with BB821410 logged.  This is an intermittent and infrequent error that can occur if Skiboot fails to get notified of the BMC mailbox shutdown prior to the re-IPL attempt.  The problem can be circumvented by doing another IPL.

 A problem was fixed for an intermittent IPL failure with  BC131705 and  BC8A1703 logged with a processor core called out.  This is a rare error and does not have a real hardware fault, so the processor core can be unguarded and used again on the next IPL.

 A problem was fixed for not always being able to change the BMC root password with the OpenBMC GUI.  However, the root password can be changed using the BMC command line.   This problem is very intermittent.

OP9_v1.19_1.192/OP910.25

09/25/18

Impact: Availability     Severity:  SPE

New features and functions

Support was disabled for erepair spare lane deployment for fabric and memory buses.  By not using the FRU spare hardware for an erepair, the affected FRUs may have to be replaced sooner.  Prior to this change, the spare lane deployment caused extra error messages during run-time diagnostics.  When the problems with spare lane deployment are corrected, this erepair feature will be enabled again in a future service pack.

System firmware changes that affect all systems

A problem was fixed for a MSI-X checkstop in CAPI mode.  This occurred intermittently when a DMA from the CAPI device targeted an address lower than 4GB and was confused for a 32-bit MSI operation.  This is now avoided by disabling the 32-bit MSI when in CAPI mode.

A performance problem was fixed for certain cases of DMA operations from the GPU to an untranslated virtual memory location.  With the fix, as much as a 10X performance improvement can occur for this type of DMA from the GPU.

A problem was fixed for L3 cache calling out a LRU Parity error too quickly for hardware that is still good.  Without the fix, ignore the L3FIR[28] LRU Parity errors unless they are very persistent with 30 or more occurrences per day.

A problem was fixed for a processor core hang and checkstop during normal operations.  This failure occurs only rarely on a race condition in the processor state machine.

A problem was fixed for a failure in DDR4 RCD (Register Clock Driver) memory initialization that causes half of the DIMM memory to be unusable after an IPL.  This is an intermittent problem where the memory can sometimes be recovered by doing another IPL.  The error is not a hardware problem with the DIMM but it is an error in the initialization sequence needed get the DIMM ready for normal operations.  This supersedes an earlier fix delivered in OP910.22 that intermittently failed to correct the problem.

OP9_v1.19.1.189/ OP910.24

08/16/18

Impact: Availability    Severity:  SPE

New features and functions

Support was added for 24x7 On-Chip Controller (OCC) counter data collection.  It allows a customer to monitor utilization and throughput of memory, buses and other system components. The data it collects is stored in system memory and the firmware provides a call interface for applications to read out this data.

Support was added for parity error checking of the GPU data on the NVLink Datalink Layer (NDL), providing earlier memory fault detection and recovery retries to eliminate transient faults.  

System firmware changes that affect all systems

A problem was fixed for a GPU NVLINK writing out of range to a MMIO section of memory with byte-enabled writes that caused a machine check.  With the fix, the out of range write is handled (detected) to cause a process core dump, but leaves the system in a usable state.

A problem was fixed for GPU workloads using unified memory with address translation service (ATS) sometimes hanging after resetting the GPUs.  The trigger for the failure was putting the NPU in the fenced state via the "NPU Fence State" register with SCOM address 0x5011696.  With the fix, the GPU fencing is handled using the NTL (NVLink Transaction Layer) reset register bits instead.

A problem was fixed for NPU log messages that were missing the CPU chip identifiers.  With the fix, CPU taking the HMI (Host Maintenance Interrupt) is listed along with the NPU FIR register values.

A problem was fixed for the On-Chip Controller (OCC) not being able communicate to the GPUs for thermal monitoring or power capping..  This means the GPUs could overheat or consume too much power for the configuration.  The GPUs will continue to operate with the last power cap that was sent.  The fans will increase to the maximum speed while in this mode where the OCC cannot read the GPU temperatures.

A problem was fixed for the On-Chip Controller inadvertently disabling the MMIO ATSD flush bits, thereby potentially reducing the performance of the address translation service (ATS) unified memory for the GPU.

A problem was fixed for user applications timing out on the GPU operation for accessing the address translation service (ATS) unified memory, causing an HMI and system termination.  With the fix, the ATSD timeout has been disabled, so the user applications can wait for GPU read or write operations to be completed without regard for the time needed for the operation.

A problem was fixed for the SBE timer being stuck and unavailable to the host applications.  This forces OPAL to use legacy timer loops for timers at the cost of additional processor bandwidth.  Here are the messages that are logged for the problem that occurs on every boot:

[  194.494559313,3] SBE: Timer stuck, falling back to OPAL pollers.

[  194.494624185,3] SBE: You will likely have slower I2C and may have experienced increased jitter.

A problem was fixed for PCIe4 CX5 adapter performance with an increase of performance of 40% for DMA read requests.  The adapter affected is the Mellanox CX5 PCIe4 100Gb  IB CAPI with feature codes  #EC62 with CCIN 2CF1 and  #EC64 with CCIN 2CF2.  Without the fix, each read request requires a retry to work.

A problem was fixed for user code running on a GPU that can perform invalid commands to the MMIO space and cause an HMI that brings down the system.  With the fix, ill-formatted commands to the MMIO space from the GPU will not be processed as a fatal exception but responses will be set to 0xFFFFFFFF and the GPU will receive a normal response code.  The user  GPU application can look for the bad response and fail, but the system will continue running without taking an HMI, allowing all other workloads to continue normally.

A problem was fixed in Petitboot V1.7.2  for Petitboot exiting to the shell with xCAT genesis in the menu when trying to do a network boot.  Petitboot was timing out when trying to access the ftpserver but it was not doing the network re-queries necessary for a proper retry.  If this error happens on a system, it can be made to boot with the following two steps:

1) Type the word "exit" and press enter key.  This brings it back to petitboot menu.

2) Press the enter key again to start the boot of the xCAT image.

OP9_v1.19.1.172 / OP910.22

06/22/18

Impact: Data    Severity:   HIPER

New features and functions

Support was added to provide the processor VPD data for the serial number and part number on the host OS.  The information can be found in the /proc/device-tree/vpd/root-node-vpd directory path.  For example, the following directory path contains the serial-number file for a processor:

" /proc/device-tree/vpd/root-node-vpd@a000/enclosure@1e00/backplane@800/processor@1000/serial-number".

System firmware changes that affect all systems

HIPER/Pervasive:   A firmware change was made to address a rare case where a memory correctable error on POWER9 servers may result in an undetected corruption of data.

A problem has been fixed to not guard processor cores on memory checkstop errors resulting from a GPU failure.  If this problem occurs, the processor cores can be restored by manually clearing the guard records.

A problem has been fixed for the NPU register data logging to include critical information for NVLINK failures such as the CPU chip identifiers.  This information is needed to be able to isolate the cause of the NVLINK faults.

A problem has been fixed for systems unexpectedly running with all processors at lower frequencies than would be expected for Workload Optimized Frequency (WOF)  ultra-turbo mode.  There was no eSEL or callout for the processor causing the error that disabled the WOF mode.  With the fix, there is an eSEL and callout for the WOF fault that identifies the errant processor that needs to be replaced.

A problem has been fixed for a PCIe adaper running in CAPP mode having a missing MMIO Base Address Register (BAR) entry that causes a failure of the adapter and  a fence off of two of the four ports of the adapter.

A problem has been fixed for a slow start up of a process that can occur when the system had been previously in an idle state.

A problem has been fixed for a TOD error that can cause a soft lockup of the kernel.  A 'soft lockup' is defined as a bug that causes the kernel to loop in kernel mode for more than 20 seconds, without giving other tasks a chance to run. The current stack trace is displayed upon detection and, by default, the system will stay locked up.

A problem was fixed for a failure in DDR4 RCD (Register Clock Driver) memory initialization that causes half of the DIMM memory to be unusable after an IPL.  This is an intermittent problem where the memory can sometimes be recovered by doing another IPL.  The error is not a hardware problem with the DIMM but it is an error in the initialization sequence needed get the DIMM ready for normal operations.

A problem was fixed for a processor core that cannot be awakened or a timeout in the On Chip Controller when switching Workload Optimized Frequency (WOF) modes from disabled to enabled.  These errors can cause a reduction in performance by running with fewer cores or by running at the safe mode frequencies.

OP9_v1.19.1.160 / OP910.21

05/18/18

Impact: Availability    Severity:   SPE

New features and functions

Support to enable Call Home ESELs to allow system data such as On-Chip Controller (OCC) telemetry to be collected remotely.

Support has been removed from XIVE interrupt controller for the store EOI operation.  Hardware has limitations which would require a sync after each store EOI to make sure the MMIO operations that change the ESB state are ordered. This would be performance prohibitive and the PCI Host Bridges (PHBs) do not support the synchronization.

System firmware changes that affect all systems

A problem was fixed for extraneous error logging and console messages for nonexistent NPU registers whenever a processor error occurs.

A problem was fixed for a false call out of a processor on a INTCQFIR[27].  This FIR bit should not call out the processor as the processor has not failed.  The error is recoverable and should only serve as an early warning indication.

A problem was fixed for transactional memory that could result in a wrong answer for processes using it.  This is a rare problem requiring L2 cache failures that can affect the process determining correctly if a transaction has completed.

A problem was fixed for Workload Optimized Frequency (WOF) where parts may have been manufactured with bad IQ data that requires filtering to prevent WOF from being disabled.

A problem was fixed for the opal-prd service consuming 100% of CPU during and after boot to the host.  This is an infrequent intermittent problem that can be circumvented by a reboot of the system.

A problem was fixed for VRMs drawing current over the specification.  This occurred whenever heavy work loads went above 372 amps with WOF enabled.  At 372 amps, a rollover to value "0" for the current erroneously occurred and this allowed the frequency of the processors in the system to exceed the normally expected values.

A problem was fixed for the wrong DIMM being called out on over-temperature failures with B1xx2A30 errors logged  This should be a rare failure as it requires a DIMM to exceed its maximum specified operating temperature.

A problem has been fixed to clean up memory after a GPU has failed.  This fix fences off failed GPUs on a GPU reset.  The fencing ensures that access to memory behind the links will not lead to HMIs. but instead SUE's will be populated in cache.  Before installing this fix, the NVIDIA Tesla driver must be updated in the Linux OS to version level 396.26 as a prerequisite. Feature #EC4J provides the NVIDIA Tesla V100 GPU with NVLINK Air-Cooled (16 GB) that requires the updated driver.  Without this driver update, a GPU that has faulted and gone through a GPU reset can cause a Terminate Immediate (TI) or HMI  for the system.  The Tesla CUDA driver can be obtained at the direct NVIDIA link of "http://www.nvidia.com/download/driverResults.aspx/134380/en-us":

In response to recently reported security vulnerabilities, this firmware update is being released to address Common Vulnerabilities and Exposures issue number CVE-2017-5754 with firmware initializations augmenting an earlier fix provided in FW level OP910.10.  Operating System updates are required in conjunction with the new FW level for addressing CVE-2017-5754.

New features and functions (not related to above CVE)

Support for voltage-droop monitors (VDM) to provide for improved system reliability during periods of unstable voltage from the power supply.  The P9 processor uses an adaptive clock strategy to reduce the system power usage during power supply droop events by embedding analog VDMs that direct a digital phase-locked loop (DPLL) to immediately reduce clock frequency in response to the droop event

Support for Workload Optimized Frequency (WOF).  This feature provides the maximum processor frequency in order to increase system performance based on workload characteristics.

Support was added for using "ipmitool mc info" from the host OS to get the BMC firmware level.

Support was added to increase the number of NPU2 register contents dumped for NVLINK Hypervisor Maintenance Interrupts (HMIs) and to add logging for the HMI actions.

Support was added to make the Self Boot Engine (SBE) fault indicator bits recoverable.  This means if a SBE seeprom error occurs, recovery action will be taken to prevent an IPL failure or system outage.

System firmware changes that affect all systems

A problem was fixed for an On-Chip Controller (OCC) not going active caused by a race condition in the initialization of the OCCs.  This problem is intermittent and can be resolved by a re-IPL of the system.

A problem was fixed for the BMC journal file getting overwritten with network change notifications when there is a IPv6 router in the local subnet.  

A problem was fixed for the BMC version fields not being set as shown by "ipmitool mc info" and the Petitboot System Information UI.  The BMC can be accessed by SSH  (secured shell) login and the following command run to show the BMC firmware level:  "cat /etc/os-release".  Look for the "VERSION=" string that has the BMC version identifier appended to it.

A problem was fixed for the display of the power supply output outage that in one instance was showing as 390V instead of 12V.  The voltage is at the right level but recent revisions of the power supply firmware had a change in how the output voltage was calculated, causing the displayed values to read too high.

A problem was fixed for VLAN ID showing as "Disabled" with the "ipmitool lan print 1" after the VLAN was set by inband by the OS.  The VLAN is set correctly and functional, but the display of the VLAN information, while initially correct, went to "Disabled" during the first minute after the operation.

A problem was fixed for no amber fault LEDs being lit (or SELs reported) for front or rear fan rotors that have a RPM of zero due to blockage or other hardware error.

A problem was fixed for the host failing during a reset of the BMC when a host to BMC message had a time out.  This problem is rare as the host normally stays up and running when the BMC is reset.

A problem was fixed for multi-rotor failures in a fan not causing a system shutdown, making it possible for the system to fail from an overheat condition that could be destructive to other system FRUs.  This problem is rare as it requires that more than one rotor fail in a system fan at the same time.

A problem was fixed for a change or enablement of the NTP time server not forcing a network time synchronization, potentially leaving the BMC local time different from the network time.  This problem can be circumvented by a reset of the BMC.

A problem was fixed for a BMC reset causing the On-Chip Controller (OCC) to fail and the system going into Safe mode.  This is an infrequent problem that is triggered if a BMC reset and a OCC reset happen at the same time such that the BMC is unable to respond to OCC messages, forcing the OCC into a failed state.

A problem was fixed for error log "BC8A2502 - IPMI::RC_INVALID_SENDRECV" occurring  during the system IPL.  The On-Chip Controller (OCC) error is automatically recovered, so the error log does not impact the system.

A problem was fixed for error log " BC8A2507 - IPMI::RC_SENSOR_NOT_PRESENT" that can occur on a system power on if the BMC was reset at system runtime previously.  When the BC8A2507  error occurs, the host uses the default value for the sensor data.  The problem will persist for the IPL until the BMC is reset.

A problem was fixed for a power supply FQPSPPW0034M error persisting with enclosure fault LEDs lit even after the power supply problem has been corrected.  The fault can be triggered by a momentary loss of AC or by unplugging and plugging AC into the power supply.

A problem was fixed for Coherent Accelerator Processor Proxy (CAPP) mode for the PCI Host Bridge (PHB) to improve DMA write performance by enabling channel tag streaming for the PHB.  With this enabled, the DMA write does not have to wait for a response before sending a new write command on the bus.

A problem was fixed for the Open-Power Flash tool "pflash" failing with a blocklevel_smart_erase error during a pflash.  This problem is infrequent and is triggered if pflash detects a smart erase fits entirely within one erase block.

A problem was fixed in the Petitboot user interface to handle cursor mode arrow keys for the VT100 'application' cursor to prevent mis-interpreting an arrow key as an escape key in some situations.  For more information on the VT100 cursor keys, see http://www.tldp.org/HOWTO/Keyboard-and-Console-HOWTO-21.html.

A problem was fixed in the Petitboot user interface to cancel the autoboot if the user has exited the Petitboot user interface.  This prevents the user dropping to the shell and then having the machine boot on them instead of waiting until the user is ready for the boot.

A problem was fixed in the Petitboot parsing of manually-specified configuration files that caused the parser to create file paths relative to the downloaded file's path, not the original remote path.

A problem was fixed for a failure to IPL with SRC BC8A0506 logged for a Phase Lock Loop error (PLL) in the PCIe Host Bridge (PHB).  This problem is very infrequent.  The fix does the correct call out of the failed FRU, allowing the IPL to continue.

A problem was fixed for a system IPL hang  that shows in the log as the host going to a quiesce state with the OS inactive.  This is a rare problem that may be recovered by a power off and re-IPL of the system.  This problem is triggered by a higher than normal level of interrupts from the Power Supply Unit (PSU).

A problem was fixed for the VPD serial number not being updated on the replacement of a planar.  The VPD update failed with the following message: "ERROR: (ECMD): ecmd - 'putvpdkeyword' returned with error code 0x20300001 (ERROR OPENING DECODE FILE). ERROR: A problem occurred updating the serial number(OSYS:SS). Please see previous output for reason ".

A problem was fixed for the CAS latency calculation for memory to improve its accuracy to reduce the potential for DIMM failures due to memory timing errors.  Column Access Strobe (CAS) latency is the delay time between the moment a memory controller tells the memory module to access a particular memory column on a RAM module, and the moment the data from the given array location is available on the module's output pins.

A problem was fixed for clearing DIMM guard records when there was a repair marked in the VPD and that prevented the DIMM from being unguarded.  With the fix, the VPD mark will be cleared if the guard record is cleared for the FRU, allowing it to be enabled on the next IPL.

A problem was fixed for the Self Boot Engine (SBE) error identification on failure.  The SRR0/SRR1/LR/Local FI2C register are now extracted to allow the following SBE errors to now be identified:

100 - Program interrupt , promoted

101 - Instruction storage interrupt, promoted

110 - Alignment interrupt, promoted

111 - Data storage interrupt, promoted

A problem was fixed for read margins to improve the margins on DIMMs, reducing the number of DIMM failure occurrences.

A problem was fixed for the Hostboot reset to enable error recovery of Hostboot through the reset path.  Without the fix, the Self Boot Engine (SBE) fails to reboot on the Hostboot reset, preventing error recovery for the Hostboot failures.

A problem was fixed for a memory training error that could caused DIMMS to be marked as bad or memory ports to be deconfigured.  This problem is rare and triggered by an incorrect internal voltage level.

A problem was fixed for a Phase Lock Loop (PLL) error causing a checkstop but not calling out and guarding the failed hardware.  There is then a chance the failure will recur on the next IPL of the system.

A problem was fixed to reduce memory latency in memory blocks where bad memory bits have been marked.

 A problem was fixed for time and date fields being zero in Hostboot error log entries for the time/date of the error occurrence.

 A problem was fixed for an extraneous "MCBISTFIR[3]: broadcast out of sync" error during memory diagnostics if a Register Clock Driver (RCD) parity error occurs.  The "broadcast out of sync" error should be ignored when isolating the RCD fault.  This problem is triggered if the RCD parity error occurs while the DDR4 memory is in broadcast mode.

A problem was fixed for BC8A2AC5 and BC8A2AC4 errors that prevented the reading of On-Chip Controller (OCC) thermal readings from the Analog Power Subsystem Sweep (APSS) bus.  This is a very rare problem.

A problem was fixed for a processor fault that caused the master processor core to guard and prevented an IPL of the system with SRC BC13E540.   With the fix, the system will IPL up on the available processor cores.  This error only occurs if the master core is faulted.  Faults on the other cores are handled correctly and do not stop an IPL.

A problem was fixed for a flood of OPAL error messages that can occur for a processor fault.  The message "CPU ATTEMPT TO RE-ENTER FIRMWARE" appears as a large group of messages and precede the relevant error messages for the processor fault.  A reboot of the system is needed to recover from this error.

Impact:  Availability    Severity:  SPE

This Service Pack includes updates in response to Recent Security Vulnerabilities, New Features & Functions and System Firmware Updates. Details of each are below:

Response for Recent Security Vulnerabilities

In response to recently reported security vulnerabilities, this firmware update is being released to address Common Vulnerabilities and Exposures issue numbers CVE-2017-5715, CVE-2017-5753 and CVE-2017-5754. Operating System updates are required in conjunction with this FW level for CVE-2017-5753 and CVE-2017-5754.

New features and functions (not related to above CVE’s)

Support was added for increasing the number of BMC error logs from 100 to 200 and changing the error log to roll over old entries when full instead of stopping the logging of errors. Without this feature, the error log would get full at 100 entries and error logging would be stopped until some of the error logs were purged to make room for new entries.

Support was added to enable power supply redundancy.

Enable air-cooled fan control to optimize fan speeds for the temperature conditions and improve fan speed control to minimize fan speed oscillation.

Support was added for advanced power supply fault monitoring to improve fault isolation, error detection, and reliability.

Support was added for forcing a new dump type, Checkstop, if the host has a checkstop. Without this new dump, critical debug information is missing because the /var/lib/obmc_console.log does not

System firmware updates (not related to above CVE’s)

A problem was fix for intermittent processor core hangs that caused checkstops with code "NCU no response to snooped TLBIE".

A problem was fixed for fans being reported as "Nonfunctional".  This error occurred during peak loads on the BMC that tripped a watchdog process, causing the fans to speed up to the maximum speed.  An error in the fan recovery to normal speed resulted in the "Nonfunctional" status.

A problem was fixed for a processor replacement that caused extra cores to be reported as present that do not exist.  This happens if the new processor has fewer cores than the processor that is being replaced.  This problem can be recovered by doing a factory reset on the BMC.

A problem was fixed for GPU temperatures not being reported on systems that have maximum DIMM configurations for the memory.  Without the fix, reducing the number of DIMMs plugged in would make available On-Chip Controller (OCC) slots for missing GPU temperatures to be reported.

A problem was fixed for the host time inadvertently changing when a BMC time change is requested in NTP mode with Split ownership.  The problem can be recovered by IPLing to the host and the NTP server will correct the host time.

A problem was fixed for the host time skewing ahead in time after time ownership is split and the clock has been set from the BMC.  The problem can be recovered by setting the correct time from the host.

A problem was fixed to reject the use of the path /org/openbmc on the REST API URIs.  This affects the API /org/openbmc/sensors/host/PowerSupplyRedundancy which is no longer valid.

A problem was fixed for the BMC REST server going into a retry hang with the BMC becoming unresponsive when given a REST command with a bad data format.  Without the fix, the REST server will repeatedly retry the bad command, causing a denial of service for all other users of the BMC.

A problem was fixed for an On-Chip Controller (OCC) read failure with ERRNO=11 during a IPL.  This intermittent problem was caused by an overflow of the total system power value from the OCC.  The system can be recovered by retrying the IPL.

A problem was fixed for the ECC error recovery.  Error recovery was not working and the ECC errors would prevent the boot.

A problem was fixed for an intermittent power on failure with message "Error in mapper call to get service name".  To recover from this problem. power cycle the BMC and try the boot again.

A problem was fixed for an On-Chip Controller (OCC) read failure with ERRNO=19 during a power off of the system.  This intermittent problem is an extraneous errror log  and can be ignored.as the power off is successful.

A problem was fixed for an intermittent error message when activating firmware during a firmware update.  This extraneous error message occurred with moderate frequency.  This is internal server 500 error message returned on the REST enumerate request.  The error message can be ignored because there is not a problem with the firmware activate.

A problem was fixed for the power button LED not blinking when in the standby state (not powered on).  Without the fix, the power button always has a solid green LED, regardless of power on or power off state.

A problem was fixed for intermittent host checkstops caused by NCU and PCI time-out mismatches.  PCI timeouts that are longer than NCU timeouts may cause checkstops on the host.
