Comment # 9 on bug 1190608 from Bunte Katze

@Michael Pujos 

I did already try nvidia.prime=intel with 5.14.2-1-default, but that changed
nothing. The nvidia driver appears to not be the culprit.

As Takashi Iwai advised, I tried a later kernel from
https://download.opensuse.org/repositories/Kernel:/stable/standard/
(5.14.5-1.gfdb6afd-default), which worked, and continued working as I installed
the nvidia kernel module and switched back from intel to nvidia. (I am
currently writing this on that new setup.)

Do you think it is still necessary for bug diagnostics to disable the udev
power management rules?
(https://bugzilla.opensuse.org/show_bug.cgi?id=1190608#c7)
I will have a hard time doing any file modifications, since I can only get to
the broken kernel by booting a readonly btrfs snapshot - which fails to boot.
(It should probably be possible to choose a previous kernel from the boot menu?
I can try if you think it will help figure out the bug, even though 5.14.5
turned out working fine.)

Unfortunately, snapper even cleaned out my previous working setup (kernel
5.14.1) before I could increase the NUMBER_LIMIT in /etc/snapper/configs/root.
