5.1-RELEASE-p2/i386

>Description:

	vinum resetconfig seems to render the vinum configuration
	extremely unstable.  In about 1/3 of the resetconfig attempts
	on two different machines running 5.1, it produced a kernel
	panic.  On one machine, after resetconfig panicked the machine,
	it would also panic on every vinum create.
	This occurred with both IDE aswell as SCSI disks.
	I can't at the moment provide a crash dump.  Maybe also the
	problem is already known.  If not, I could take some effort
	to produce a trace.

>How-To-Repeat:

	Install 5.1, play around with vinum create+resetconfig.
