Raising importance based on BAT results
Comment 2 Ricardo 2017-02-14 15:13:56 UTC 
Looking at the results from igt fast drm-tip 4.10.0-rc8 6f8a1e0 SNB the test passes in the QA side reported in today's FastFeedback
Comment 3 Ricardo 2017-02-14 15:28:12 UTC 
lowering again... the test seems fail on a sequential runs
Comment 4 Marta Löfstedt 2017-03-03 07:52:17 UTC 
last line in dmesg:
[  353.691361] [IGT] kms_pipe_crc_basic: starting subtest suspend-read-crc-pipe-A

I.e. this is one of the busg 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
Comment 5 Marta Löfstedt 2017-03-03 08:26:39 UTC 
Move to staging?
Comment 6 Jani Saarinen 2017-03-27 11:19:34 UTC 
One occurrence only and data missing to properly debug.
Will be re-opened when reoccurres.
