Issue: Softlockup with udev-worker during video playback via Firefox
browsers on wayland/Xorg with AMD GPU driver
Expected: stable system, and smooth video playback
What actually happens: system freezes requiring a sysreq sequence. CU
soft lockup udev-worker message in logs. DrKonqi rate-limiting for
crashes.
Steps to reproduce:
1. Open a Firefox browser such as Zen, LibreWolf, Floorp, or Firefox itself.
2. Navigate to an online video playback service
3. start playing videos
4. Switch desktops or let system idle till screen lock
5. system freezes, cannot interact
Key observations
* Happens with Snap Firefox and Flatpak Zen. but NOT with Chrome based
browsers.
* Does not happen with youtube playback but with other codecs and or sources
* occurs on both wayland and xorg
"watchdog: BUG: soft lockup - CPU#0 stuck for 32s! [(udev-worker):574]" found
in journalctl -b -1
* "drkonqi-coredump-launcher: ... not starting since we tried this too often
recently" also in logs
