NetBSD 3.1 kernel panic in arlad

[david l goodrich]

I just had a NetBSD 3.1 Xen domU kernel panic in arlad last
night.  This is a XEN3_DOMU kernel, stock, from ftp.netbsd.org.

Does anybody want more information?  This box isn't really doing
anything, so I'll just let it sit at the db> prompt for the next
couple days.
