Frequent GPU crashes w/ amdgpu

[herrhotzenplotz]

Summary

I've been getting a lot of spam regarding some Vulkan stuff when playing videos with multimedia/mpv recently:

[vo/gpu-next/libplacebo] vkQueueSubmit2: VK_ERROR_UNKNOWN (../src/vulkan/command.c:533)

I don't remember when this started to occur.
The video playback itself is also very glitchy and seems to be skipping forwards and backwards or even over the majority of frames.
Trying to stop mpv is only possible via a SIGINT/^C.

After restarting mpv multiple times (without forcing any video output driver) I usually get a GPU crash (video output first goes blank and then comes back with garbage output).
All this is under X11 via X.org (i3+picom as window manager and compositor, not that it should matter here).

Once the GPU has crashed I am still able to ssh into the system but there's no apparent log anywhere.
dmesg doesn't say anything.

#480 has the smell of the same or related bug but I can't really tell since I haven't tested the 6.12 module.

FTR, this is a pkgbased system.

Let me know if you need more info and how I can possibly assist debugging this.
