I am running Debian Unstable and encounter 100% CPU usage after some
hours, reproducible. I have to shut off the system with sysrq, I can't
shut it down the normal way as it is non-responsive.

I tried 6.12.9 and 6.12.8.

6.12.8 gave some dmesg error messages:

Jan 13 11:09:44 ryz kernel: amdgpu 0000:08:00.0: amdgpu: Dumping IP State
Jan 13 11:09:48 ryz kernel: [drm:amdgpu_dm_atomic_check [amdgpu]] *ERROR* [CRTC:73:crtc-0] hw_done or flip_done timed out
Jan 13 11:09:55 ryz kernel: amdgpu 0000:08:00.0: amdgpu: failed to write reg 28b4 wait reg 28c6
Jan 13 11:10:00 ryz kernel: sysrq: Keyboard mode set to system default
Jan 13 11:10:00 ryz kernel: sysrq: This sysrq operation is disabled.
Jan 13 11:10:00 ryz kernel: sysrq: This sysrq operation is disabled.
Jan 13 11:10:01 ryz kernel: sysrq: Emergency Sync


6.12.9 doesn't gave me them, but it doesn't list sysrq calls either, so
I assume it didn't manage to store them in dmesg.

I remember the first occurrence last Friday, some mesa packages were
updated and I assume it was running 6.12.8 according to the apt logs.




Please tell me which further info you need to track down the issue.
