** Description changed: 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 with fancy visual transitions or let system idle till screen lock or manually log out 5. System freezes, cannot interact, although can reboot via SysReq sequence 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 * sometimes happens when moving desktops in plasma, upon arriving at the desktop that has Firefox/Zen * sometimes happens after logging back in after timeout in plasma * has occurred across multiple Ubuntu versions * using open-source drivers * EDIT: I'll add the only other oddity I've noticed is that scrolling pages, usually blog posts, in Brave often results in momentary and intermittent unresponsiveness or lagginess, often in full screen (F11), while out of full-screen on the same page and instance will not elicit such behaviour. Firefox and derivatives do not demonstrate such performance issues. Important observation: When I scrape the video URL from the browser and play it directly in VLC, it plays without issues, despite using the same video source that might cause freeze issues with Firefox/Zen. This suggests the problem lies in the browser's specific implementation of hardware video decoding/acceleration and its interaction with the radeon driver Mesa stack, rather than the fundamental inability if the driver to decode the video itself.

Disable both "use recommended performance settings" and "use acceleration when possible" selections in Firefox and related browser's Preferences panel. 2.

I'm running the radeon driver, and have always done so, ever since installing Ubuntu on this laptop several versions ago.
