I am stuck on this one, and I won't be near my BDW for a few days. A bisect would be very much appreciated.
Ping for the bisect ... Ben: Please always set NEEDINFO when requestion something from our QA engineers, otherwise it won't show up in their filters.

I have pushed a fix in IGT (1552aa21124cabe762862bb414490510415a2b2d) for this, however there is still a bug on BDW blocking a proper test (see drm/i915: Fix disabled semaphores). I've pinged Daniel to merge that patch. Assigning to him for now.
