Bug Description
As stated in the summary, my PC can't suspend anymore after kernel upgrade.
When I click suspend from desktop:
- The screen gets blank
- (sometimes) Screen then shows up for a short time, then gets blank again
- Now PC ist "dead", no reaction an keyboard, mouse and so on.
- Even a CTR-ALT-DEL didn't show any reaction.
- There is still some activity (HD-Led flashing)
- The PC is "reachable" via network, but trying to ssh into it will not work (no response after entering password)
- I have to reboot, either by power the PC off by pressing the power button longer or by using "Magic SysRq" keyboard sequence
When I rollback (I use systemback) to Kernel 5.13.0-35-generic suspend works!
