Dave, Alex,
 there's an odd bugreport on bugzilla, where Artem is seeing an odd
early-boot failure.

That one almost certainly has nothing to do with you guys, but see the
later odd (and apparently unrelated) report about some AMD graphics
firmware issue and a black screen.

Odd.  I have a similar picasso based raven laptop and it is working
fine with F31 and the latest 5.4.8 kernel.  I think the firmware is a
red herring as the driver won't load without it so if you don't have
it installed, the driver won't be running in the first place.  I'll
follow up in the bug report and ask him to file a new bug about the
amdgpu issue to avoid cluttering up the current report.
