Xorg.0.log

Hi!

I'm using archlinux x86_64 with latest mesa,nouveau from the official repos and
nouveau-fw from the aur. (Hw: NVE6: GTX 660)
I get random screen freezes every 10 min - 1 hour in a gnome session.
Once the screen freezes the mouse and sometimes the keyboard goes unresponsive
too  .(even the leds for num lock do not respond)
I can switch to another tty (I get nouveau messages here: "cannot idle
channel..."), kill the running gnome session, switch back then restart the
gnome session but the restarted gnome session gets back to the very last image
before the freeze and it is unresponsive. After 10-30 secs that restarted
session crashes and I cannot get X working again without a complete restart.

X log attached.
