Description of problem:
I was executing this command (a system scan with clamAV) when the system suddenly froze: sudo clamscan -r --infected --exclude-dir=/.snapshots --exclude-dir=/proc --exclude-dir=/sys --exclude-dir=/dev --exclude-dir=/media --exclude-dir=/mnt /

Apparently something related to amdgpu and dmub_psr, so probably nothing to do with clamAV. Perhaps related to the following bug: https://gitlab.freedesktop.org/drm/amd/-/issues/2220

The system could not recover and had to hard reset.
