Description Tim Bishop freebsd_committer freebsd_triage 2008-11-12 23:10:00 UTC 
	When running mksnap_ffs on the above filesystem the system
	completely freezes up. The console is unresponsive, and
	even after a couple of hours there is still no response. I
	guess it deadlocked, but it may just be being incredibly
	slow.

	Some discussion on freebsd-stable:

	http://lists.freebsd.org/pipermail/freebsd-stable/2008-November/046524.html

Fix: This fix was provided to me in response to my post on
	freebsd-stable. It's against 7-STABLE. I can see what it's
	doing, but don't understand the bigger picture enough to
	know if it's sensible.
How-To-Repeat: 	paladin# cd /u2/.snap
	paladin# mksnap_ffs /u2 test.1
