I'm adding some more info as I discover here that my kernel is tainted: * SMP kernel oops on an officially SMP incapable processor
I guess the reason is that my ryzon 1600 has an hw bug and I need to disable its C6 state by writing in some MSR. I don't think this is related to my problem, but can verify the bug still happens with MSR untouched if you think it is worth it.
