mesa upgrade from 24.2.8 causes unexplainable freezes on amdgpu

After a recent Gentoo upgrade (starting with mesa) I experienced crashes via Chromium. My crashes can be described a freezing screen after which kworker/u32:0+amdgpu-reset-dev causes an extremely high load. Typically from having a YouTube video running or working with SketchUp Web. I have already reverted the firmware back to the release as of 20241110, but the device still crashes.

After which I downgraded to mesa 24.2.8, until which the freeze did not occur anymore (yet).
