This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- eoan' to 'verification-done-eoan'. If the problem still exists, change the tag 'verification-needed-eoan' to 'verification-failed-eoan'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

For Eoan, this patch can be applied with some context adjustment. For Focal, there is a SAUCE patch which turned off timeout setting for benchmarks and tm that needs to be reverted first, and this patch can be applied with some context adjustment too == Test == Patch tested on PowerPC and it works as expected. == Regression Potential == Low, changes limited to testing tools for PowerPC. == Original Bug Report == Issue found on Power9 node baltar with B-5.3 (5.3.0-41.33~18.04.1-generic) # selftests: benchmarks: futex_bench # test: futex_bench # tags: git_version:unknown # time = 52.042224 # not ok 5 selftests: benchmarks: futex_bench # TIMEOUT # selftests: dscr: dscr_sysfs_test # test: dscr_sysfs_test # tags: git_version:unknown # not ok 6 selftests: dscr: dscr_sysfs_test # TIMEOUT Need to check if this has something to do with the timeout setting like in bug 1864626 ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-image-5.3.0-40-generic 5.3.0-40.32~18.04.1 ProcVersionSignature: Ubuntu 5.3.0-40.32~18.04.1-generic 5.3.18 Uname: Linux 5.3.0-40-generic ppc64le ApportVersion: 2.20.9-0ubuntu7.11 Architecture: ppc64el Date: Tue Feb 25 11:23:58 2020 ProcLoadAvg: 1.28 22.46 46.59 3/1347 62287 ProcLocks: 1: POSIX ADVISORY WRITE 3837 00:18:562 0 EOF 2: POSIX ADVISORY WRITE 3864 00:18:588 0 EOF 3: FLOCK ADVISORY WRITE 4515 00:18:463 0 EOF 4: FLOCK ADVISORY WRITE 3844 00:18:579 0 EOF 5: POSIX ADVISORY WRITE 1820 00:18:343 0 EOF ProcSwaps: Filename Type Size Used Priority /swap.img file 8388544 0 -2 ProcVersion: Linux version 5.3.0-40-generic (buildd@bos02-ppc64el-007) (gcc version 7.4.0 (Ubuntu 7.4.0-1ubuntu1~18.04.1)) #32~18.04.1-Ubuntu SMP Mon Feb 3 14:05:15 UTC 2020 SourcePackage: linux-signed-hwe UpgradeStatus: No upgrade log present (probably fresh install) VarLogDump_list: total 0 cpu_cores: Number of cores present = 40 cpu_coreson: Number of cores online = 39 cpu_dscr: DSCR is 9 cpu_freq: min: 2.862 GHz (cpu 79) max: 2.945 GHz (cpu 81) avg: 2.903 GHz cpu_runmode: Could not retrieve current diagnostics mode, No kernel interface to firmware cpu_smt: SMT=4 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1864642/+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
