See

More info. I also tried recent i386 kernel
(201210040810Z/i386/installation/cdrom/boot.iso)

It crashes the same way.

>How-To-Repeat:

>Fix:

As suggested here:
http://mail-index.netbsd.org/tech-kern/2012/10/23/msg014166.html
commenting panic("ciss: dead"); in sys/dev/ic/ciss.c "fixes" the panic().
Results shown by printf:
http://mail-index.netbsd.org/tech-kern/2012/10/24/msg014221.html
The machine is now fully usable, up for 5 days without issue.
