If this is an ironlake with a DP output it's a know issue which seems
to pop up every once in a while. Otherwise we need to take a look
here. If so can you please boot with drm.debug=0xe, reproduce the
issue and attach the complete dmesg?

Also does 3.10-rc1 work (since you mention -rc2 specifically and there
wasn't really a lot going into that for drm/i915).

Thanks, Daniel
