--- Comment #6 from Dmitrii Tcvetkov <demfloro at demfloro.ru> ---
It works good on kernel 4.6.3 and earlier, problem is since 4.7. I just tried
to find conditions of the bug.

I reverted patch
"0006-drm-nouveau-disp-sor-gf119-both-links-use-the-same-training register"
from commit a8953c52b95167b5d21a66f0859751570271d834 and nouveau loads about 1
second, screen does not become black. System behaves like on 4.6 kernel.

Unfortunately I can't fully understand impact of this reversion on different
video adapters. Can you send it to dri-devel mailing list?
