>Description:
	with the latest lfs changes, newfs_lfs a /obj partition, mount
	it, and run make obj which creates a directory hierarchy under
	/obj.  kernel panics.  i don't have a tracedump from that, but
	can reproduce this consistently.  reboot, mount /obj again, and
	immediate panic:

partial handcopied trace is below, i have the complete crashdump if it's
useful.
