Well it seemed to work fine, but when I came home from work today, it looks like
the network was dead.  I tried to login via a serial console, and after I
entered root as the username, and hit enter, nothing really happened.  I tried
to login via terminal, and I wasn't even able to type a username.  I hit
ctl-alt-esc, and got a db> prompt.  Typed panic, and got a good dump.  The
kernel and core is being uploaded to leaf right now.  They are *.11.
