Hence, customers that have a Power 9 Whitherspoon (equipped with GPUs) will experience a crash on their server when using NVIDIA's toolkit. The server will crash with the following hardware failing message: Unrecoverable Hardware Failure, (Critical) A system checkstop occurred (AffectedSubsystem: Canister/Appliance, PID: 19703), Resolved: 0 In this case, a `NCUFIR[10] tlbie master timeout` has been observed by only starting the NVIDIA ATS driver. This issue is being triggered because the NMU logic is getting stuck when a page is upgraded from RO -> RW without a following tlbie. This is addressed with the following patches: bd5050e38aec3055ff4257ade987d808ac93b582 powerpc/mm/radix: Change pte relax sequence to handle nest MMU hang e4c1112c3fc503fc78379fa61450bfda3f0717fe powerpc/mm: Change function prototype 044003b52a78bcbda7103633c351da16505096cf powerpc/mm/radix: Move function from radix.h to pgtable-radix.c f069ff396d657ac7bdb5de866c3ec28b8d08d953 powerpc/mm/hugetlb: Update huge_ptep_set_access_flags to call __ptep_set_access_flags directly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1789772/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
