Comment 3 for bug 509186

Thank you for reporting this bug, Brian. Take a look at https://wiki.ubuntu.com/X/Troubleshooting/Freeze for more information about this kind of bug and especially how to get a batchbuffer dump. Other things that would be useful is disabling any OpenGL stuff and also try some newer and older mainline kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/ (see also https://wiki.ubuntu.com/KernelTeam/MainlineBuilds) to see if any of them stop the freezes.
