I applied the patch on Kernel 4.8.0-rc8-00771-g8ab293e: result is a stable
system as before, so at least it didn't introduce a regression.

Then I disabled the override for my card below:

Result is the same as without your patch: black screen and non responsive
system.

Should I also revert "drm/radeon: load different smc firmware on some =
SI
variants"?
