** Description changed: This is a scripted bug report about ADT failures while running linux tests for linux/5.13.0-23.23 on impish. Whether this is caused by the dep8 tests of the tested source or the kernel has yet to be determined. + + This test was previously being skipped. After recent test changes, it's + now showing up as a failure. Not a regression. ubuntu_kernel_selftests.powerpc/security:spectre_v2 consistently failing on 5.13 and 5.11 Found failing on: - Impish/linux 5.13.0-23.23 - Hirsute/linux 5.11.0-42.46 (passed on first run, though failing after retrigger) - Foal/hwe-5.13 5.13.0-23.23~20.04.1 - Focal/hwe-5.11 5.11.0-42.46~20.04.1 - + Impish/linux 5.13.0-23.23 + Hirsute/linux 5.11.0-42.46 (passed on first run, though failing after retrigger) + Foal/hwe-5.13 5.13.0-23.23~20.04.1 + Focal/hwe-5.11 5.11.0-42.46~20.04.1 23:45:31 DEBUG| [stdout] # selftests: powerpc/security: spectre_v2 23:45:31 DEBUG| [stdout] # test: spectre_v2 23:45:31 DEBUG| [stdout] # tags: git_version:d9c024c2-dirty 23:45:50 DEBUG| [stdout] # sysfs reports: 'Mitigation: Software count cache flush, Software link stack flush' 23:45:50 DEBUG| [stdout] # PM_BR_PRED_CCACHE: result 2147483649 running/enabled 19680067308 23:45:50 DEBUG| [stdout] # PM_BR_MPRED_CCACHE: result 2147475077 running/enabled 19680064034 23:45:50 DEBUG| [stdout] # PM_BR_PRED_PCACHE: result 0 running/enabled 19680062840 23:45:50 DEBUG| [stdout] # PM_BR_MPRED_PCACHE: result 0 running/enabled 19680061722 23:45:50 DEBUG| [stdout] # Miss percent 99 % 23:45:50 DEBUG| [stdout] # Branch misses > 15% unexpected in this configuration! 23:45:50 DEBUG| [stdout] # Possible mis-match between reported & actual mitigation 23:45:50 DEBUG| [stdout] # failure: spectre_v2 23:45:50 DEBUG| [stdout] not ok 1 selftests: powerpc/security: spectre_v2 # exit=1 23:45:50 DEBUG| [stdout] make: Leaving directory '/tmp/autopkgtest.XkeXuO/build.i7C/src/autotest/client/tmp/ubuntu_kernel_selftests/src/linux/tools/testing/selftests/powerpc/security' - Testing failed on: ppc64el: https://autopkgtest.ubuntu.com/results/autopkgtest-impish/impish/ppc64el/l/linux/20211204_000820_141a2@/log.gz
