Note that there are two ways the test can fail: Failure A: (kms_setmode:1555) CRITICAL: Test assertion failure function check_timings, file kms_setmode.c:493: (kms_setmode:1555) CRITICAL: Failed assertion: accuracy < line_time(kmode) (kms_setmode:1555) CRITICAL: vblank accuracy (21.857us, 0.1%) worse than a scanline (20.677us) Failure B: (kms_setmode:1532) CRITICAL: Test assertion failure function check_timings, file kms_setmode.c:519: (kms_setmode:1532) CRITICAL: Failed assertion: fabs(mean - expected) < 1.718 * stddev (kms_setmode:1532) CRITICAL: vblank interval differs from modeline! expected 16665.6us, measured 16717us +- 2.758us, difference 51.3us (18.6 sigma) For SNB-shards is fails on all runs with "Failure B" from CI_DRM_2907 - CI_DRM_2956 For HSW-shards: the test pass 9 times between CI_DRM_2907 - CI_DRM_2956, "Failure A" 7 times and the rest "Failure B". For KBL-shards: the test pass 8 times between CI_DRM_2908 - CI_DRM_2956, the rest is "Failure B". Also, I can reproduce this on my BDW i5NUC so far I have 100% "Failure B".</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
