--- Comment #2 from Daniel Vetter <daniel at ffwll.ch> ---
Hm, we seem to miss exactly a frame ...

A few questions:
- How reproducible is this? I'm running some of the mentioned tests in an
endless loop on my ilk yet, it seems solid.
- Does booting with drm_kms_helper.poll=0 help?
- Does this only happen on specific ilk/ivb machines (e.g. specific monitors
connected) or on all of them? What about snb?
- On a quick lock the ivb machine has only VGA connected. Does the issue also
happen on when other outputs instead of VGA are connected, maybe with different
screens ...
