This may help: commit 4d90f2d507ab4634e9e1923de3a6769ac0aa71fa Author: Ville Syrjälä <ville.syrjala@linux.intel.com> AuthorDate: Thu Oct 12 16:02:01 2017 +0300 Commit: Ville Syrjälä <ville.syrjala@linux.intel.com> CommitDate: Thu Oct 12 21:18:00 2017 +0300 drm/i915: Start tracking PSR state in crtc state Add the minimal amount of PSR tracking into the crtc state. This allows precomputing the possibility of using PSR correctly, and it means we can safely call the psr enable/disable functions for any DP endcoder.
Unfortunately the problem appears to persist in linux-next, which already has that commit.
First of all. Sorry about spam. This is mass update for our bugs. Sorry if you feel this annoying but with this trying to understand if bug still valid or not.
