Dear Maintainer,

Problem happens when hardware accelerated video playback is used
(VA-API). It can be in standalone video player (Totem) or in browsers
like Firefox or Chromium. A lot of advertisements are videos with
autoplayback. System often hangs by visiting unfortunate website.
The problem is triggered no every time, but pretty often.

The problem is reported upstream:
https://gitlab.freedesktop.org/mesa/mesa/-/issues/13402

In the past I've solved this by removing package
'mesa-va-drivers'. But with mesa 25.3.2-2 mesa-va-drivers is removed
and all va drivers are autmotically enabled by mesa-libgallium
package.

Currently I have to manually remove following symlinks to avoid system
hangs:

```
sudo rm /usr/lib/x86_64-linux-gnu/dri/radeonsi_drv_video.so
sudo rm /usr/lib/x86_64-linux-gnu/dri/r600_drv_video.so
```
