Kernel log with PGRAPH_ERROR statements

Yesterday build a full nouveau system and tried the suspend. Although upon resume my LVDS-0 never went on. The system was fully working and managed to reboot without a problem.

Hm, I don't see any suspend/resume cycles with nouveau loaded in your log files.  There's a couple of suspends with the NVIDIA binary driver, but that's it.

That particular PGRAPH error is "normal", and not related to LVDS not coming back.

Suspent to Ram is working properly now. Bug fixed with the following commit
