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:
diff --git a/drivers/gpu/drm/radeon/si_dpm.c b/drivers/gpu/drm/radeon/si_dpm.c
index e6abc09..bcaa675 100644

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"?</pre>
