Just another datapoint on this...

I have this disease with a (non-reference) Asus RX480 in an Asus Sabertooth
Gen3 R2.0 (or something like that, I can never remember exactly what it's
called).  It does not fix itself when I reboot.

If I turn off IOMMU entirely in the BIOS (not just the memory hole), then it
goes away (along, of course, with my iommu functionality, which I'm not
thrilled about).

I can also boot and avoid the spam with iommu=3Dpt or iommu=3Dsoft.

I have also seen brief "flashing screen" artifacts in xorg, which=
 get more
frequent if I stress the system (doesn't need to be graphics related).  Whe=

these correlate with the log spam, I'm not entirely sure.  I think it may, =
but
it might instead have been related to a firmware loading problem that I've
since resolved... I'd have to try it again to be sure.

Like the OP, when I get the log spam I also see this:

May 22 14:23:21 moneypit kernel: amdgpu: [powerplay] [AVFS] Something is
broken. See log!
May 22 14:23:21 moneypit kernel: amdgpu: [powerplay] Can't find requested
voltage id in vdd_dep_on_sclk table!
