Daniel: I'm encountering a problem with the drm-intel-nightly branch in your drm-intel repository. The symptom is that when I boot my laptop, at some point during the start-up procedure the screen goes totally blank, as though the backlight were turned off, and it remains that way. I can't tell if the backlight really is off -- it may be that there's just nothing being displayed -- and playing with the screen-brightness function keys doesn't help.
Git bisect located the source of the problem as commit d91a2cb8e510 (drm/i915: Add 180 degree primary plane rotation support). The problem occurs when I boot a kernel built from that commit, and it doesn't occur when I boot a kernel built from the preceding commit (19ac737dc3c3). If necessary, I can get debugging info by logging in over a network connection. Tell me what you need.
