Comment 3 Jose Roberto de Souza 2019-09-26 17:17:33 UTC
The CRC did not matched between sink and source while PSR was active, so it was disabled and will remain disabled until next boot, causing user to lost some power savings but it will avoid any glitches and image corruption.

For now we are not trying to re-enable PSR after errors, PSR caused a lot of problems in the past and we are taking a safe approach now.

So changing importance to low.
