System: NetBSD proven 1.5T NetBSD 1.5T (PROVEN) #5: Tue Apr 17 20:14:46 EDT 2001 woods@proven:/work/woods/NetBSD-src/sys/arch/i386/compile/PROVEN i386
Architecture: i386
Machine: i386

>Description:

	I accidentally left a sample RAID configuration file in
	/etc/raid0.conf and experienced the following crash on boot:

>How-To-Repeat:

	create a valid /etc/raid0.conf file for which no components have
	ever been initialised and then reboot

>Fix:

	unknown

	but the work-around is to make sure there's no /etc/raid0.conf
	when there's not supposed to be one.... :-)
