This looks similar to

https://bugs.freedesktop.org/show_bug.cgi?id=91883

From that bug you can find Maarten's patch to move LUT after vblank evasion. Maybe give it a go with that patch applied?
Comment 2 Jari Tahvanainen 2017-04-11 11:26:18 UTC 
This test has not failed in last 100 executions ...
See https://intel-gfx-ci.01.org/CI/igt@kms_busy@basic-flip-default-c.html.

Jani, if you agree please set this as RESOLVED, otherwise set status to REOPENED.
Comment 3 Jani Saarinen 2017-04-11 11:43:14 UTC 
OK, lets resolve it as works for me now. If pops up lets re-open.
No failure see on a/b/c
