--- Comment #3 from dwagner jb5sgc1n.nya@20mm.eu --- The good news: Your draft fix works for me - the system no longer crashes when woken up from S3 with HDMI display off. Thanks a lot for this really important fix.
The mediocre news: Lots of scary messages are logged by amdgpu, as reported by "dmesg". I'll split this into separate parts:
Part 1: Scary amdgpu messages when booting (with display on, only console, no X11):

The bad news: I originally thought that this fix would probably also fix system crashes that invariably occur to me when I use "xlock" to blank the screen of an X11 session, and then turn off the HDMI display. (The crashes in that scenario do not occur immediately after switching the display off, but after what seems to be a fixed period of time - I assume related to some dpms function or alike used by xlock.) However, that xlock/then-display-off/then-wait/then-crash bug still occurs even with your fix. Should I open a separate ticket on this?
