--- Comment #9 from Brian Lovin <brian.j.lovin at intel.com> ---
Here's what I've found for the bad commit; it appears to be in the middle of a
patch series Ville commited - Someone will have to take a look at what's going
on.

093e3f134e2eff13503f708b81aecc2501e7aecb is the first bad commit

drm/i915: Hold the pps mutex across the whole panel power enable sequence


This commit doesn't revert cleanly on drm-intel-testing from 11/7, which was
all I had time to test for now.
