I'll try that tomorrow, but unless it's captured by dmesg at the next
boot, it won't do much good; I don't have time to read it before the
reboot. There are no panic messages in /var/log/messages now, though,
so I suspect it won't help.
I rebooted a few more times since my posting. I can say that it
happens after /etc/rc.d/ldconfig runs. I suspect it's timing-related,
since I was able to boot -- and start services -- after commenting out
most of rc.conf.
I also think that it's getting a uvm_fault during the panic, which is
why I'm not getting a dump.
The obvious thing to try is a serial console; unfortunately, I won't be
able to do that until next week.
