> I wonder if you think this has something to do with ufs?

I'm not sure, but I just got a similar panic (though unfortunately,
did not get a backtrace. Working on reproducing it now so I can get a
dump/backtrace). I thought it might be related to the commit for
sys/vm/vm_page.c, but that might just be coincidence.

> This is RELENG_7 from Fri Nov 23 13:08:36

Mine is RELENG_7 from 11/28/2007, and the panic occurred when I was
running buildworld.

I'll report back once I'm able to reproduce it, but my panic was the same:

vm_page_insert: page already inserted
