Closed issue by RicArch97 on void-packages repository

https://github.com/void-linux/void-packages/issues/37439

Description:
<!-- Don't request update of package. We have a script for that. https://repo-default.voidlinux.org/void-updates/void-updates.txt. However, a quality pull request may help. -->
### System

* xuname:  
  `Void 5.18.2_1 x86_64 AuthenticAMD uptodate rrrmFFFFFFFFFFFFFFFFFFFF`
* package:  
  `linux5.18 5.18.2_1` and `firefox 100.0.2_1`

### Expected behavior

Watching YouTube video's on Firefox should work without the entire AMDGPU module crashing. Note that I have VAAPI enabled in Firefox. It did work on previous kernels without issues. Watching a video in google-chrome does not cause any crashes however.

### Actual behavior

The AMDGPU module crashes apparently, as there is no longer video output. Sounds still keeps playing. Switching TTY's is no longer possible at that point though, can only press the reset button on my PC to reboot.

### Steps to reproduce the behavior

On kernel 5.18.2, enable VAAPI in Firefox by setting `media.ffmpeg.vaapi.enabled` to `true` in `about:config`. I personally use the Sway window manager and run Firefox with `MOZ_ENABLE_WAYLAND=1` to enable the Wayland backend and `MOZ_DISABLE_RDD_SANDBOX=1` to make sure VAAPI works correctly, as stated in the Arch wiki.
Then, watch a YouTube video.
