Can you please retest this with the most current 6.12.32-1 and report back if the issue persist? If so can you please again provide a full log? If this will look like an upstream issue we might ask you to fill an upstream issue at https://gitlab.freedesktop.org/drm/amd/, but we would like to see if the issue still persist on most recent version and have a look at a fresh boot log.
