>Release:        FreeBSD 2.0-BUILT-19950522  i386
>Environment:

	PC 486 with IDE drive, booted via NFS on a FreeBSD-current PC.
	(i.e., the 'diskless' PC boots without using its IDE drive)

	It gets its root and swap partitions via NFS.

>Description:

	Panic when trying to disklabel the IDE drive attached on the
	'diskless' PC.

>How-To-Repeat:

	# disklabel -w -r /dev/wd0s2 labelname

-> console messages
	fixlabel: invalid magic
	fixlabel: invalid magic
	panic: vwakeup: neg numoutput

	Notes:

		- I used wd0s2. That's obviously wrong, but I'm not sure
		  that's relevant.
		- the filesystem containing the inode for /dev/wd0s2
		  was NFS-mounted
		- Slice 1 is a DOS partition on that PC. Slice 2 was an
		  extended DOS partition with no previous disklabel, but
		  with its ID changed to become a FreeBSD partition.
		- the drive was previously completely unlabelled.

>Fix:
	
	I finally managed to correctly disklabel that disk, after many
	tries.
