Firefox has VAAPI disabled by default, but it can be enabled by the user. * the fix for noble will be provided via the full version backport from oracular [ Test Plan ] * Set up a system with an AMD GPU running Ubuntu 24.10 with kernel 6.11 * Open Firefox * Navigate to `about:config` * Search `media.ffmpeg.vaapi.enabled` * Enable the setting by clicking the toggle button * Restart Firefox * Play different videos on x.com or youtube.com (I don't have a reliable reproducer unfortunately) * Ensure that there are no green artifacts on the video playback * Ensure that the system didn't lock up * 10 minutes of scrolling through videos was generally enough to trigger the bug in my testing. Sometimes I could only get the green artifacts, other times I could get the system to lock up. [ Where problems could occur ] * The scope of the change is limited to the VAAPI driver for AMD GPUs ( /usr/lib/x86_64-linux-gnu/dri/radeonsi_drv_video.so ) An issue with the change may break video playback. But, as this bug demonstrated, a bug in the video acceleration driver may also bring down the whole system... [ Original Description ] It turns out that amdgpu in kernel 6.11 on the Ryzen 6850U is quite crashy and laggy. I have attached the previous boot log which shows a lot of errors. It does not seem to like firefox. Behavior visible is that it hangs, then tries resets, fails to reset and then the screen is unusable so I sysrq reboot it.
