The latest 2.6.28-11-generic#37 kernel (amd64) has frozen twice in the last 24 hours on my PC, ie locked up completely (with indicator lights flashing) and needing a hard reset by holding down the power button.

The first time I was using it (I was moving the mouse), but the second time it was just idling when it locked some time between 3:50 and 7:44 am, as shown in the syslog:

This is on the latest Jaunty. It's a Dell XPS M1530 that was running nvidia 185.13 the first time it locked up, and 180.41 the second time. There's no information in any of the logs - syslog shows the last message at 3:50.

Prior to this, I haven't had any lockups for quite some time (it was the iwlagn driver causing it in Intrepid but that bug was fixed some time ago).
