igt@kms_busy@basic-flip-default-b hangs on CI
http://benchsrv.fi.intel.com/archive/results/CI_IGT_test/CI_DRM_2164/fi-bxt-j4205/igt@kms_busy@basic-flip-default-b.html

One occurrence but reporting that still...

After this test is marked as known issue.

This needs to be a Highest+Blocker.
Comment 3 Chris Wilson 2017-02-13 16:55:17 UTC 
There's no relevant debug information; what is there says that it didn't even start igt@kms_busy@basic-flip-default-b
Comment 4 Jani Saarinen 2017-02-14 08:08:08 UTC 
This hanged only once, should we move this to staging to follow?
Comment 5 Jani Saarinen 2017-02-16 08:49:10 UTC 
What can we do to provide necessary info when this happens again?
If not possible please add code in i915 to provide good information to debug further.
Comment 6 Marta Löfstedt 2017-03-03 07:45:36 UTC 
last line in dmesg:
[  421.699056] [IGT] kms_pipe_crc_basic: starting subtest suspend-read-crc-pipe-B
I.e. this is one of the bugs 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

Hi Jani, what do you mean by test-c?
Comment 10 Jani Saarinen 2017-03-10 10:17:27 UTC 
Copy paste issue. Was trying to say kms_busy@basic-flip-default-c test.
Comment 11 Jani Saarinen 2017-03-27 10:36:26 UTC 
Not seen fo the long time.
Resolving works for me.
Comment 12 Jani Saarinen 2017-03-27 10:52:47 UTC 
Whitelisted again on CI too
