Bug#864349: nouveau: fifo: write fault at 0000e5f000 engine 1b [CE2] client 18 [GR_CE] reason 02 [PTE] on channel 8

[Peter Makholm <peter@makholm.net>]

Package: xserver-xorg-video-nouveau
Version: 1:1.0.13-3

I have the same experience on a Dell desktop. The X session freezes and 
I can move the mouse around, but nothing else is responding. Even the 
NumLock key in non-responsive.

Relevant output from dmesg:
---------------------------
