<pre>I can reproduce this on a SKL NUC with DP + HDMI when running the kms_plane
tests on -nightly from today (2016-06-23). About half of the tests fail
consistently. Running with just DP or HDMI works fine, which I find a bit odd
if it's just a matter of waiting for vblank before the pipe is fully on. I'll
look into this some more.</pre>
