This test to be marked unstable / known until further decisions.
Comment 2 Jani Saarinen 2017-02-14 10:43:32 UTC
Next run passes again.
Comment 3 Dorota Czaplejewicz 2017-03-02 18:54:23 UTC
I tried this with drm-tip: 2017y-02m-27d-07h-11m-41s on Celeron(R) CPU G3900, 32 times, but nothing came up.
Comment 4 Marta Löfstedt 2017-03-03 07:40:09 UTC
last line in dmesg:
[  215.328295] [IGT] gem_exec_suspend: starting subtest basic-S3
I.e. this is one of the bug where we have lost contact with the DUT during suspend-resume and can't get any information on what that has happened.
We are working on a solution to use pstore to maybe get more information when this happens.

I set lower importance

Well, it happened again yesterday: https://intel-gfx-ci.01.org/CI/CI_DRM_2424/fi-skl-6260u/igt@gem_exec_suspend@basic-s3.html

I am un-archiving the issue!
