Please keep me in CC.
I receive a warning in drivers/gpu/drm/i915/intel_display.c:3869. This
happens when I'm on a console, the screen has gone into power save and I
press a key to wake it up.
This doesn't happen when I'm in X.
Kernel is Vanilla 3.11.2.

This is a segfault on kernel 3.11.3. There's no X started yet, but one
s2ram cycle.
Attached is the complete dmesg with drm.debug=0xe or on
