Hi Daniel,
A bug was opened against the Ubuntu kernel[0]. It was found that reverting the
following commit resolved this bug:
commit 657445fe8660100ad174600ebfa61536392b7624

Revert "drm/i915: revert eDP bpp clamping code changes"
The regression was introduced as of v3.10-rc2 and affects a large number of end
users.
I see this code has gone back and forth a few times, so I was wondering if we
could get some feedback. The revert of commit 657445f was tested aginst 3.11
stable and could not be done cleanly, so I had to make some modifications. The
modifications I made for 3.11 are in [PATCH 1/1]. The revert can't be done
cleanly against 3.12 neither. The modifications I made for 3.11 will not work
cleanly on 3.12 due to recent changes in 3.12, such as commit 7984211.
However, I can create a patch specific for 3.12 if you think this is the best
way to go.
Thanks,
Joe
