Selecting the platform and updating the importance. Note that the run this failed on was a KASAN test, i.e. the kernel was a bit slower than normal. Dropping the priority, since it is only seen with KASAN. It needs to be fixed though! Adding tag into "Whiteboard" field - ReadyForDev The bug still active *Status is correct *Platform is included *Feature is included *Priority and Severity correctly set *Logs included (In reply to Martin Peres from comment #3) > Dropping the priority, since it is only seen with KASAN. It needs to be > fixed though! Hello, Is there any update on this bug? Thank you. Elisabet, please note that that was seen on special KASAN build.

In particular this bug > doesn't cover incompletes or dmesg-fail. This bug is only about tests failing due to "Failed assertion: es->current_seq == es->last_seq + o->seq_step". The history thing in cibuglog is useless. If an issue is filed on a (machine,test) pair, all other issues for that pair is "covered" and never seen in cibuglog.

Seems that we are a bit too slow processing in one vblank, especially with the slower machines. It depends on machines capability of scheduling and how well the tasks are executed. Sometimes, it may require more time to complete. If we fail to fix the test we will take a hit on test coverage. I don't expect any noticeable flickering on userspace to happen, if we fail to complete tasks in one vblank.

I went through the last 2 weeks and the only other delta I could find is this: https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_252/fi-snb-2520m/igt@kms_flip@plain-flip-ts-check-interruptible.html with is 4 vblanks, so no, not always by 1. Maybe we could still relax the test a bit, let's say accept the fact that we may have +2 vblanks until completion of the test. A CI Bug Log filter associated to this bug has been updated:
