FreeBSD 5.2-CURRENT #1: Sun Feb 1 15:53:50 EST 2004
from source cvsuped early Saturday morning, I get repeatable
zpanics with:
#0 doadump () at /usr/src/sys/kern/kern_shutdown.c:240
#1 0xc04eb0d9 in boot (howto=256) at /usr/src/sys/kern/kern_shutdown.c:374
#2 0xc04eb3a7 in __panic () at /usr/src/sys/kern/kern_shutdown.c:552

at /usr/src/sys/kern/kern_malloc.c:255
on a system with:
real memory = 536854528 (511 MB)
avail memory = 520171520 (496 MB)
I have a kernel core with debugging enabled and the matching
config file available on request.
