I guess due to va-driver-all. This is a catch all package that installs all the available drivers. If you know which one you need (and that's not intel-media-va-driver), you can safely uninstall and keep only the driver suitable for your machine. > On your side, what would be good behaviour if I tryed to propose a patch? FWIW, I patch is currently worked on upstream. In any case, a proper fix would be to ensure that __vaDriverInit is built without SSE3 and above.
