>Description:
	Trying to root on an msdosfs partition panics before it
	gets anywhere.  Here's a backtrace copied by hand.

	>       panic+0x55
	>       lockmgr+0x2af
	>       msdosfs_lock+0x22
	>       vn_lock+0x3f
	>       deget+0xcc
	>       msdosfs_root+0x23
	>       main+0x3eb
	> 

>How-To-Repeat:
	Find a machine with an msdos partition on it,
	(doesn't have to contain any netbsd files AFAICS)
	Ensure that the msdosfs partition is correctly
	labelled (mine's wd0e, and I checked by mounting and
	using it)

	boot -a netbsd.GENERIC

	at the root device prompt, say wd0e and watch it go bang.
