[Problem]
GPU lockup 

[Original Description]
This has happened approximately 3 times today - only on the 3rd time was I able
to ssh into the system and examine things.  I believe the test case is
scrolling in firefox with compiz on.  I saw the following in my dmesg.

I was able to recreate this again by dragging around the world in googleearth.
This time I lost network connectivity.

I was able to recreate it with compiz disabled and also with 2.6.32-19 which I
was running for quite some time with no issues.

 I got netconsole setup and sending messages to another system these are the
last messages before the signal went dead.

It is no longer possible to communicate with computer ship flash.
