--- Comment #7 from Johannes Hirte johannes.hirte@datenkhaos.de --- some more infos: I see the mentioned error in the logs during normal work, but no other problems. When resuming from S3 suspend, the display stays black and I find dozens of those dcn10_verify_allow_pstate_change_high.cold warnings in the log after reboot. Still happens with kernel 5.3-rc6.
