I think I may have hit the same problem; I'm going to stay connected to the console and see if it happens again; this is what I see currently with the back-trace:

db> bt

I just updated to I think 268921 earlier today and this is the first time I've had a panic (HEAD-268921 that is)

I'll try to get some more data if I can get it back up and running.
