	Kernel panic: invalbuf: dirty bufs

	Seems to happen under moderate disk activity.  It happened twice
	so far during my attempt to move several directories from one
	disk to another.  I do not see any real issue with the disk
	traffic, except that I am moving from a gmirror device to a
	normal device, on different ata attach points.  The gmirror is
	on a fast SATA (300) interface and the other device is on a
	slower (150) SATA interface.  I have 4 SATA interfaces on this
	system, the two standard ata interfaces on the mother board and
	two SATA interfaces to attach my real SATA disks.  So, the
	gmirror gets the fast one and everyone else gets the slower one.

	I have vmcore if it is of interest to anyone.
