>Description:
sytem panic on kldload ng_bpf.ko then options NETGRAPH_BPF is built in kernell
>How-To-Repeat:
1. update to latest 7.2: cvsup -L 2 -h cvsup.FreeBSD.org /usr/share/examples/cvsup/stable-supfile
2. in kernel config add: 
#device	bpf
options	NETGRAPH
options	NETGRAPH_BPF
options	NETGRAPH_CAR
options	NETGRAPH_ETHER
options	NETGRAPH_IFACE
options	NETGRAPH_KSOCKET
options	NETGRAPH_L2TP
options	NETGRAPH_NAT
options	NETGRAPH_PPP
options	NETGRAPH_PPPOE
options	NETGRAPH_PPTPGRE
options	NETGRAPH_SOCKET
options	NETGRAPH_TCPMSS
options	NETGRAPH_TEE

3. buid and install kernell with options from 2, restart

4. install and run latest dnsmasq

5. kldload ng_bpf.ko


Another way: install and run mpd5 as pppoe internet client and pptp server, then connect to vpn server from internet.
I think it same bug in botf cases.
