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.
