<pre>While consecutively running the extended list I have noticed that the kms_flip
subtests following igt@kms_flip@bo-too-big, are failing on my BDW NUCi5. When
this happens I typically get vblank time out as below:

*ERROR* [CRTC:39:pipe B] flip_done timed out"
However, if I remove the kms_fbcon_fbt subtest fbc-suspend the kms_flip thest
are fine.
I am currently running drm-tip git@bc781a3cf, but judging from extended results
from farm2 BDWs this has been going on for quite a while.</pre>
