Thanks for the suggestion.
Just tried this, no luck. Also tried 'runpm=0' (but apparently that's
for laptop only so ...)

Even with cg_mask=0, I still see this in amdgpu_pm_info, not sure if
that's expected of if somehow the option was ignored ?

I'm not really sure what to try next. I unfortunately don't have
access to any other card or any other motherboard I could use to test
:/
(Or anything fancy like pcie bus analyzer or stuff like that).

My understanding of the first error message that shows up is that the
card itself tries to make an access to a memory zone it's not allowed
to right ?
