Have you run kldxref after installing modules?

In CURRENT netgraph method xxx_shutdown() is called _after_ all hooks
has been disconnected.

I think this is not very good idea. In some cases node needs to send some
data before shutdown, for example ng_pppoe should close all active sessions
sending PADT message, otherwise we have got hanging sessions on remote side.
Some other protocols implementations may require sending of data before
shutting down.
