This bug is present in Lucid as well, unfortunately. My symptoms are largely the same:
* Complete system freeze, including X and the mouse * Kernel panic (cannot SSH into the box) * No obvious pattern; will reboot multiple times in an hour, and then be fine for five or six hours or more * Occasionally system hangs with music looping, but is more often random and not clearly associated with an activity * Last reported issue is the ratelimit.d problem with Pulseaudio I have filed what may be a duplicate bug at: <a href="https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/568549">https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/568549</a> It does not appear to be related to the proprietary NVidia drivers, as I've downgraded to the non-proprietary versions and am still experiencing the issue.
