System: NetBSD minas-morgul.hitzemann.org 2.0G NetBSD 2.0G (MINAS-MORGUL) #2: Mon Sep 13 00:58:06 CEST 2004 simon@minas-morgul.hitzemann.org:/usr/src/sys/arch/i386/compile/MINAS-MORGUL i386
Architecture: i386
Machine: i386
>Description:
	
	When running the vinum binary with the /dev/vinum/control device set to the minor number
	the binary supects it to be it crashes the system. This also happens if the control device
	is missing at all, even when running "vinum makedev". All other minor numbers simply state
	that the device is not configured.
>How-To-Repeat:
	
	rm /dev/vinum/control
	vinum makedev

	or:
	mknod /dev/vinum/control c vinum 262142 (at least that's what vinum wants on my system)
	vinum

	produces:
	uvm_fault(0xcd0572b0, 0, 0, 1) -> 0xe
	fatal page fault in supervisor mode
