I found 5 of these Oopses starting in June 9 with  kernel 7.0.10-1.

Found out that some of these oopses happened while waking up for 
hibernation or running LLM's.
(some hangs when waking up did not leave traces in the logs)

It happens  almost every 2 days.

Hibernation worked great before (factoring out  the issues with the 
parport module race when booting).
