For the record:

On my system it needs to be "LIBVA_DRIVER_NAME" and "i915",
but, yeah, that helps :-)

I put that into my .bashrc for the time being as

export LIBVA_DRVER_NAME=i915

Thanks !

Thanks, that is definitely not supported by intel-media-driver and
shouldn't be loaded in the first place. Reported upstream.

Which Intel CPU/GPU do you have? If the instruction is not supported, libva
shouldn't load the driver for your's.
