Odd I couldn't even boot my system with the dGPU as primary after
rebuilding the kernel. It got hung up in the IOMMU driver (loads of
AMD-Vi IOMMU errors) which I wasn't able to capture because it panic'ed
before loading the network stack.
Bizarre.
I'll keep trying.

Great, not sure if that is a good or a bad news.
Anyway going to revert the change for now. Does anybody volunteer to
figure out why interrupts sometimes doesn't work correctly on Raven?
What does "doesn't work correctly?" My workstation is a Raven1 (Ryzen
2400G) and other than the TTM bulk move issue has been perfectly
stable (through suspend/resumes too I might add).
Anything I could test with my devel raven?
The problem seems to be that on some boards IH handling doesn't work as
it should.
Can you try to disable the onboard graphics and try again?
If that still doesn't work there is a DRM_DEBUG in amdgpu_ih_process(),
make that a DRM_ERROR and send me the resulting dmesg of loading amdgpu
(but don't start any UMD).
Thanks,
Christian.

drm/amdgpu: remove fence fallback
DC doesn't seem to have a fallback path either.
So when interrupts doesn't work any more we are pretty much
busted no
matter what.
