igt@kms_pipe_crc_basic@suspend-read-crc-pipe-a hanged on CI

https://intel-gfx-ci.01.org/CI/fi-ilk-650.html
=>
dmesg:
https://intel-gfx-ci.01.org/CI/CI_DRM_2176/fi-ilk-650/dmesg-during.log

Not much info, but after this report marking bug as known issue on CI.
Comment 1 Marta Löfstedt 2017-03-03 07:46:59 UTC 
last line in dmesg:
[  406.001435] [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 2 Marta Löfstedt 2017-03-03 08:27:03 UTC 
Move to staging
Comment 3 Jani Saarinen 2017-03-28 06:53:25 UTC 
This was only one occurrence. Whitelisting from CI
