netbsd-5 panic

[Jeff Rizzo <riz%tastylime.net@localhost>]

I have a system that's been crashing periodically with 4.99.72, and I
just upgraded it to netbsd-5 in the hopes of debugging whatever's going on.

Apart from the backtrace, what else should I get next time this happens?

+j

GENERIC kernel, amd64, and here's what's in ddb when it happens:
