	System: NetBSD mage.starwolf.com 1.4Z NetBSD 1.4Z (MAGE) #1: Sun Jun 4 12:15:38 PDT 2000 greywolf@mage.starwolf.com:/usr/src/sys/arch/i386/compile/MAGE i386
	Machine: P-II/300
	Memory: 96MB
	Kernel: 1.4Z(-current) of 4 June 2000

>Description:
	The soft-dependency stuff still doesn't seem to work right --
	it crashed again.  To wit:

	This from -current of today, 4 June 2000...last cvs update done at
	about noon.

	I'm less concerned about the invalid address mappings at the end
	than I am of the fact that softdeps still doesn't work.

	PII/300, 96MB memory; crashed running savecore.
	Startup got as far as "Checking for core dump" and panicked.
