panic with /sys/vm/vm_contig.c (v1.31)

Hi,

I am having a reproducible kernel panic with /sys/vm/vm_contig.c
	$FreeBSD: src/sys/vm/vm_contig.c,v 1.31 2004/03/02 08:25:58 alc Exp $
on my system. The panic happens very early during boot process
and the system hangs hard after that (have to press reset).

Attached are the boot messages from a failed boot (1.31 of vm_contig.c)
and a successful boot (1.30 of vm_contig.c). If a complete kernel
config file is needed, I can also provide it.
