	Seems we have a winner. I removed the following code, recompiled kernel,
	and everything seems to be working ok. Problem of course being that I need
	most of the following code for the purposes of this box.

	options         IPFIREWALL              #firewall
	options         IPFIREWALL_VERBOSE      #enable logging to syslogd(8)
	options         IPFIREWALL_VERBOSE_LIMIT=100    #limit verbosity
	options         IPDIVERT                #divert sockets
	options         IPSTEALTH               #support for stealth forwarding
	options         TCP_DROP_SYNFIN         #drop TCP packets with SYN+FIN
	options         DUMMYNET
	options         DEVICE_POLLING
	options         HZ=1000
