I'm not so sure. On <a class="bz_bug_link
bz_status_NEW "
title="NEW --- - UVD initialization fails while dGPU is powered on by DRI_PRIME"
href="show_bug.cgi?id=75234">bug 75234</a>, the UVD initialization only fails after a
runtime power management event, while in this case, it fails right from the
start.
For this bug, does disabling runtime power management help? Try appending
radeon.runpm=0 to the kernel command line in grub.</pre>
