Forwarding this bug from Ubuntu reporter Brian Murray: http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/564181 [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.

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.

Does disabling smooth scrolling in firefox help?

(In reply to comment #6) > Does disabling smooth scrolling in firefox help? I was able to recreate this most successfully using googleearth. Additionally, I installed a previous version of the Ubuntu package xserver-xorg-video-ati 1:6.12.192-2ubuntu2 and I am no longer able to recreate the bug.
