------- Comment From [email protected] 2017-07-04 09:03 EDT------- This CMVC defect is being cancelled by the CDE Bridge because the corresponding CQ Defect [SW354783] was transferred out of the bridge domain. Here are the additional details: New Subsystem = ppc_triage New Release = unspecified New Component = ubuntu_linux New OwnerInfo = Chavez, Luciano ([email protected]) To continue tracking this issue, please follow CQ defect [SW354783].
Opened defect SW355478 on new fail to see if it is the same issue. I made sev 1 since system in XMON right now and is preventing further testing. Like I mentioned earlier, the fail could be related to this defect. For this defect... The "Oops: Kernel access of bad area, sig: 11 [#1]" in the logs happens during HTX run. On the reboot (that happened ~30 minutes after first error), I saw partition hang/crash. I had to use ipmitool to power down system. Current xmon crash in SW355478 / 142348 is different than one being tracked in this bug. Will wait for recreate of original issue. The FlashGT HST team still needs to recreate this issue. SW357236 "HTX fail during superpipe 128 per LUN testing...during Guardband Testing" is now marked as a duplicate of this SW354783. Per comment from JVP (SW357236 submitter), he is attempting a recreate again with the latest Firmware for his Tuleta-L. We will monitor that attempt at recreate, and reopen this SW354783 if a new recreate is achieved. This original recreate attempt on Firestone, fsbmc30, may be delayed, as it is currently tied up with debugging a link training issue. <Automated Update> The severity of defect SW354783 was increased from 2 to 1 because defect SW358210 was rejected as the duplicate of defect SW354783 and the severity of defect SW358210 was higher than 2 Defect submitter, Dion is out on vacation until 7/11. So we can make progress on this most recent recreate, SW358210 dup'd to this SW354783, I request the defect Owner, Luciano/ScreenTeam, to please reopen this SW354783 and continue live debug on the held system from SW358210: #=#=# 2016-07-05 17:12:28 (CDT) #=#=# Action = [reopen] I'm not quite sure how to handle this (I'll ping Mark Smith) defect. Dion's defect SW358210 : FlashGT STC GA3: capiredp01: TMF timed out and Unable to handle kernel paging request before system drops into xmon debugger, was running HTX for superpipe with 1600 virtual luns across 4 FlashGT NVME cards was just dup'd to this one. That system is currently in XMON debugger now and can be debugged to 1) verify it is same issue and 2) maybe try to find root cause (his defect can be re-opened if not the same issue). #=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=# Not able to look SW358210. Looking into machine capiredp01 box.

HTX (hxesurelock) process has segfaulted and kernel has crashed while generating core. Attached kernel logs with bug . Machine is sitting in xmon and available for debug.

(In reply to comment #26) > Vipin, > I cannot ssh to capiredfsp.aus.stglabs.ibm.com (dev/FipSdev). Is the machine > still in xmon? Yes its still sitting in xmon. You can open console via IPMI. Please see comment 22 for machine access details. Just wanted to point out the send_tmf timeout (at the end of the kernel log) before the crash even though I am not sure it is the cause. The system is in xmon. Please advise if additional debug data need to be collected. Thanks. Snippet at the end of the kernel log: [ 8801.190528] cxlflash 0007:00:00.0: send_tmf: TMF timed out!

At this point they seem like different issues so I am opening up 2 different defects. I've already opened up defect SW354759 for the first set of htx errors and assigned to htx_screen. This defect is for issue that happened after 17th reboot (Jun 1 @ 6am). On the 18th reboot (Jun 1 @ 7am), the shutdown -r command failed... I had to manually power down system. I guess I will open to surelock_screen first since it seems similar to the one Dion opened up while running 128 virtual LUNs per port (defect http://w3.rchland.ibm.com/projects/bestquest/?defect=SW353881) . For this fail, other exercisers eventually failed also. Test Info: ============ - running Soft bootme (shutdown -r every hour) - mdt.bu + hxecom (GPUs were running). I copied a modified mdt.bu to another mdt file so I would not see any errors in htx after reboot.
