Comment 22 for bug 305458

I'm using xserver 1.6.4-2ubuntu1 (ubuntu 9.10/karmic) on r100, and am seeing a hard lock even when launching a nautilus window. Like I said, my system is hard-locked when this occurs. If I'm already ssh'd in, I can see the syslog output below for a second, then the connection gets closed. I can't ctrl-alt-f1 on the system, and there's no disk activity. I have to hold down the power button to turn off the system.

Should I log a separate bug, or reopen this bug? What other information can I provide?

Kernel is linux-image-2.6.31-13-generic (version 2.6.31-13.45, but I've seen this since karmic alpha5)
xserver-xorg-video-radeon is version 1:6.12.99+git20090825.fc74e119-0ubuntu3
