Full boot log (from journalctl -k -b bootid)

It's been doing this for a while, and I'd been advised to try a newer
kernel as there had apparently been a fair amount of nouveau related
improvements. So I tried various -rc kernels and now the final 3.17.0
kernel. It seems (although I don't have enough data to be certain)
that it's improved things slightly in that the crashes seem less
frequent now. But it obviously still crashes.

Reproducing it is simply a matter of waiting. If I leave the machine
overnight, there's a reasonable chance that it'll be crashed when I
get back into work the following morning. In terms of specific
behaviour to trigger the crash, then no, I can't really give any
information other than that I leave the machine basically idle
overnight, running one of the less demanding screensavers from
xscreensaver (cubicgrid).

I don't think it's an optimus setup, but I'm not familiar enough with
the Nvidia product range to say for sure. It's a PCI GeForce card in
a desktop machine.

By upgrading the ddx, I'm assuming you mean the xorg-x11-drv-nouveau
package? I'm already at the latest distribution supplied version (as
I am for mesa), but I guess I could look at compiling it from source
if you think it might help.
