Example of failed amdgpu boot with R9 390.

I'm running the latest Manjaro and have a Sapphire Nitro R9 390. Kernels be=
fore
4.19.x work great with amdgpu, but all kernels from 4.19.x on hang at boot,=
 and
usually don't even generate a boot log, no matter how long you wait.

However after compiling and testing the latest linux-amd-wip-git I was able=
 to
get a log so I can finally file a bug. By the way, I've gotten a few logs
before but lost them while debugging, however this time I had the sense to =
save
it.

In nay case, the error line is always the same:

AMDGPU(0): [KMS] drm report modesetting isn't supported.

This only happens if you set amdgpu.dpm=3D1 and/or amdgpu.dc=3D1 with the b=
ad
kernels. If you leave those options out amdgpu works, but things like resum=
ing
from suspend, etc. don't work.

I've attached Xorg.0.good.log to show a good boot with kernel 4.18.20, and a
Xorg.0.bad.log to show the failed boot with amd-wip-git. And by the way I've
tried numerous kernels over the last weeks and they all fail the same way, =
but
if you want me to test a specific kernel I'll be happy to do so.

Here's the grub line I use for all testing:
GRUB_CMDLINE_LINUX_DEFAULT=3D"quiet
resume=3DUUID=3Db4f71480-8fe3-43c2-99c9-fc3f5687545b libata.atapi_passthru1=
