Non-working looks the same but with
System: Kernel: 5.15.5-zen1-1-zen x86_64 bits: 64 compiler: gcc v: 11.1.0
I'm not sure exactly when this started, I think it might've been with the move to 5.15 from 5.14. I run Mixxx, the whole kernel crashes. No caps-lock-light, gotta hard reboot, etc.
Installing and rebooting into linux-lts mitigates the problem.
