journalctl from a 3.16 rc2 boot that reproduces the issue

This is kind of a follow-up to
https://bugs.freedesktop.org/show_bug.cgi?id=77599 , but the behaviour seems
different now and we're on kernel 3.16, so I figured we'd best start from
scratch.

With kernel 3.16 rc2, resuming from suspend on my GeForce 9600 GT (10de:0622)
*always* seems to fail. Screens never come out of power-saving mode, can't ssh
in. This differs from 3.15, where it sometimes succeeded and sometimes failed,
and never seemed to fail if I just booted, quickly suspended, and quickly
resumed - with 3.16 rc2, doing that causes it to fail every time.

I'll attach journalctl with drm.debug=15 from a boot where I booted to gdm,
suspended, resumed, left the system sitting for a while, then forcibly
rebooted.

This is on Fedora Rawhide, with:

kernel-3.16.0-0.rc2.git0.1.fc21.x86_64
xorg-x11-drv-nouveau-1.0.10-5.fc21.x86_64
xorg-x11-server-common-1.15.99.903-2.fc21.x86_64
