Description Martin Peres 2017-03-24 09:27:42 UTC

The machine fi-bsw-n3050 produced a fail when running igt@kms_flip@basic-flip-vs-wf_vblank on CI_DRM_2392 and has not been seen for the past 3 runs.

Relevant hunk in the piglit logs:

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.

Comment 3 Martin Peres 2017-03-29 11:28:23 UTC

Dropping the priority, since it is only seen with KASAN. It needs to be fixed though!

Comment 4 Ricardo 2017-05-09 19:32:37 UTC

Adding tag into "Whiteboard" field - ReadyForDev
The bug still active
*Status is correct
*Platform is included

Hello,
It seems that this bugs need more time, so I'm changing to NEEDINFO. Thank you.

Comment 6 Elizabeth 2017-10-11 16:30:45 UTC

No updates on this case. According to https://intel-gfx-ci.01.org/tree/drm-tip/fi-bsw-n3050.html, the test haven't failed on a while, and there is no track of the issue on https://intel-gfx-ci.01.org/cibuglog/.

Comment 7 Martin Peres 2018-02-19 10:33:10 UTC

This is stil visible on current kernels:

 - https://intel-gfx-ci.01.org/tree/drm-tip/kasan_1/fi-bsw-n3050/igt@kms_flip@basic-flip-vs-wf_vblank.html
 - https://intel-gfx-ci.01.org/tree/drm-tip/kasan_2/fi-bsw-n3050/igt@kms_flip@basic-flip-vs-wf_vblank.html
 - https://intel-gfx-ci.01.org/tree/drm-tip/kasan_4/fi-bsw-n3050/igt@kms_flip@basic-flip-vs-wf_vblank.html
 - https://intel-gfx-ci.01.org/tree/drm-tip/kasan_5/fi-bsw-n3050/igt@kms_flip@basic-flip-vs-wf_vblank.html
 

It can also pass:
https://intel-gfx-ci.01.org/tree/drm-tip/kasan_6/fi-bsw-n3050/igt@kms_flip@basic-flip-vs-wf_vblank.html

I will mark this bug as a duplicate of 100368.
