Comment 3 Marta Löfstedt 2017-12-11 10:00:12 UTC 
This looks like a regression that for the first time occurred on:
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3480/fi-kbl-r/igt@kms_pipe_crc_basic@suspend-read-crc-pipe-a.html

then it has been on each run on at least on of the igt@kms_pipe_crc_basic@suspend-read-crc-pipe-[a|b|c] subtest except on CI_DRM_3493.
Comment 4 Marta Löfstedt 2017-12-11 15:17:15 UTC 
Try-bot with revert of b68763741aa29f2541c7ca58bcb0c2bb6cb5f449

Comment 5 Marta Löfstedt 2017-12-12 07:32:24 UTC 
Result from 2 try-bot runs the issue isn't reproduced I have queued up another round:
