Package: firmware-amd-graphics
Version: 20250410-2
Severity: important

Using firmware-amd-graphics on a RV730 causes system freezes when VA-API hardware video acceleration is used for H.264 encoded content.

Installing 20210315-3~bpo10+1 has promptly eliminated the freezes for me.

I realize this is a particularly old version of the package, however I picked it specifically because it was reported to fix similar issues years ago, on RV600-class hardware, though unfortunately the conversation was years old at this point.

This problem is easily reproduced by playing a H.264 encoded file in mpv and switching VA-API acceleration on with Ctrl-H.

Testing every single version of the package to determine when exactly this regression was introduced would be time consuming: I'm available for further testing if required, however I would appreciate some assistance so I don't have to try dozens of different firmware versions.
