>Description:
OS hangs out with a seconds after first pptp-client has connected to server. It's a gateway with net/mpd5.3 configured as pppoe-client and PPTP-server for VPN-clients.
If there is just pppoe-connection then the system does not hang.
Compiling custom kernel with NETGRAPH-options changes nothing.
Freebsd-7.2R has the same issue.
Freebsd-7.0R does not have the problem.

>How-To-Repeat:
Install net/mpd5.3, configure mpd.conf as pppoe-client and pptp-server.
Connect the server to network via pppoe. Connect pptp-client to server via pppoe-link. Send some traffic to server.
