Xorg log file when X failed to recover from power save state

When resuming from suspend to ram or blank screen (power saving), mouse is
working but screen is stuck (not garbage).

After SSHing into system, it was under high load as X and kworker processes
where fighting for CPU. dmesg was full with "nouveau E[ X[2406]] nv50cal_space:
-16"
Reboot fixes the issue.

Gentoo ~AMD64
