relevant journal output

Running Fedora Rawhide, with kernel-3.15.0-0.rc1.git2.2.fc21.x86_64 ,
xorg-x11-drv-nouveau-1.0.10-1.fc21.x86_64 ,
xorg-x11-server-common-1.15.0-5.fc21.x86_64 . My hardware is:

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation G94 [GeForce 9600
GT] [10de:0622] (rev a1)

I just came home and resumed from suspend, and graphics didn't come back. Tried
sshing in and restarting X, no go - seems like nouveau crapped the bed and
wouldn't come back short of a reboot. I don't think this is reliably
reproducible unless it's only just started with a new kernel (I haven't been
seeing it on every suspend/resume cycle recently or anything), but I thought
I'd log in.

Attaching the relevant journalctl output (grepped for 'nouveau', isolated the
important time).
