Hey, all. I built -current on my i386 this morning, and then this afternoon
did an automated CD burn. My machine evidently panicked and rebooted. I don't
see anything obvious in my logs, but the only thing the box was doing out of
the ordinary was the CD burn, and since I was asleep during the crash, I don't
know if that was it or not... I've randomly seen panics in the past when my
box tried to start fixing a disk in my Memorex ATAPI CD-RW drive.`

All I know for sure:

Jan  1 15:08:50 acheron savecore: reboot after panic: pmap_unwire: invalid (unmapped) va

If I can dredge up any useful information, tell me what to do and I'll do it.
My dmesg is attached. (The only other thing I can think of is that I'd built
my new kernel, rebooted, built my new userland, and NOT then rebooted before
burning the disk... Does this matter? I didn't think it did, but I don't
*really* know that.) In the meantime, I'll see if I can reproduce the panic.
