That's my suspicion as well, since I haven't gotten any hangs so far with
radv/llvm or radv/aco when playing games, especially after aco added several
GPU hazard mitigations for Navi:

https://gitlab.freedesktop.org/mesa/mesa/blob/master/src/amd/=
compiler/README

I wonder if the above hangs are related to similar GPU hardware bugs in Nav=
i,
that weren't yet worked around in radeonsi.

I even opened one bug like that, but closed it due to assuming it's really
amdgpu problem. Not sure if I should re-open it:
