output of `dmesg`

Since switching to Nouveau, a couple of hours after booting my system, the
display will freeze up. I can still move the mouse, and I can still hear the
sound of any media-player or YouTube still running. Sometimes, I can still go
to another terminal with Ctrl-Alt-F2, sometimes not. One time when I could, I
restarted X and it would just work again.

(Additionally, the frame rate seems a bit 'stuttery' compared to the binary
NVidia drivers, especially when moving windows around and such. That may or may
not be a separate issue.)

There are a bunch of nvidia errors in my dmesg output that I do not understand.
I attached this output.

I'd be happy to provide any extra info you need, but would also much appreciate
any workaround I could use.
