Greg, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p xorg REPLACE-WITH-BUG-NUMBER Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful. Thank you for your understanding.

Before the failure, I had been looking at WebGL in Firefox, but I have no idea if that is related or not. This is the second freeze in two days. The console was completely frozen both times -- no response to the keyboard nor mouse -- but I am able to remotely login and reboot.
