Hey, all.

I was just about done writing a CD-RW and my machine froze for a moment,
and then did a spontaneous reboot.

On coming back up, I saw:

Nov 21 13:14:17 acheron savecore: reboot after panic: pmap_unwire: invalid (unma
pped) va
Nov 21 13:14:17 acheron savecore: writing core to /var/crash/netbsd.11.core
Nov 21 13:14:34 acheron savecore: writing kernel to /var/crash/netbsd.11

So, I have the core dump, I'm just not sure what to do with it. :)

My machine's running -current built yesterday, complete with SoftDep
everywhere. I'm not running update(8). I've confirmed that ioflush is

ac /root# uname -a
NetBSD 1.4P NetBSD 1.4P (MLB) #19: Sat Nov 20 14:14:29 EST 1999 i386

The crash happened just as cdrecord was finishing fixating a CD-RW. (It was
a backup, amusingly.)

I'm freshening my sources, and I'm going to rebuild, and try the backup again.
I'll also verify that I've got the latest cdrecord.

My CD stuff in my kernel config, FWIW:

cd*     at atapibus? drive ? flags 0xff0        # ATAPI CD-ROM drives
#cd*    at atapibus? drive ? flags 0x0000       # ATAPI CD-ROM drives
