>Description:
	The de driver likes to keep mbuf clusters allocated all the
	time.  This causes deadlocks in the default configuration (256
	mbuf clusters) with two de cards; the de driver will chew up
	all the mbuf clusters, and the network stack will simply
	freeze up.

>How-To-Repeat:
	The configuration in question uses one de card to talk to a
	cable modem network, and one to talk to `internal' machines.
	The problem occurs ~every time I use rsync.

>Fix:
        [None provided.]
