Does this patch help?
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:

Ok.
Should I also revert "drm/radeon: load different smc firmware on some SI variants"?
No.
