Tested 5.3-rc6. Still has the same issues. Only it's maybe actually worse
because I lose display completely when I use amdgpu.dpm=2 w/Radeon VII
multimonitor on 5.3-rc6, whereas on 5.2.9 I just got same/similar errors to
default.

I'm working a kernel fork of 5.3-rc6 where I'm reverting various things and
adding things in from Vega 10/12 and Navi to see if it helps. Haven't compiled
and tested it yet but since I know 5.3-rc6 itself boots, compiles, and
demonstrates the issue I guess it's a good base until 5.3 releases.

Any ideas anyone has are appreciated.

For now I actually find that amdgpu.dpm=0 with both 4K monitors on Radeon VII
allows for much snappier generic desktop than my previous setup with AMD+iGPU.
It's amazing how well this card runs 4K displays w/o any proper memory clock
management at all. I'm sure the gaming performance would be pretty bad tho, but
I have Windows for that for now . . .
