[Bug 545039] [NEW] Hard freeze after upgrading to Lucid

[Guilherme Salgado]

Public bug reported:

After leaving my box unattended for a few minutes, it froze and I
couldn't restart X or switch to a VT. I was able to ssh in from another
box, though, but restarting gdm wasn't enough, so I had to 'sudo reboot'
it. This is what I found in /var/log/messages afterwards.

That traceback actually seems to have happened a few times while I tried
