Bug Description
I've been experiencing random freezes (with the caps lock LED blinking, which I think means "kernel panic") with both 2.6.38-5 and 2.6.38-6 - I installed natty at *-5, so I don't know when this might have started, but 2.6.35 in maverick didn't suffer from this.
The chunk of /var/log/kern.log corresponding to the last freeze is the following, which seems truncated halfway through the backtrace:

Freezes occur between once every couple of days and a couple every day.

This continues to happen at random on my laptop - haven't seen it on my desktop yet, so it's likely hardware-specific. Any hints on gathering a backtrace for a kernel panic? I've seen instructions that require a serial port, but unless "serial" includes USB, that won't be possible on my laptop..
