I think monitoring the network for PPPoE traffic should say whether 
or not the local end is dead (no traffic == local death).  ``tcpdump 
-i iface -l not ip'' should do it.

Assuming there's no traffic, it may be necessary to install a modified 
netgraph module - one that logs when it's setting up and triggering 
timeouts.  I did this some time ago here, but could never get 
anything to lock up :(  I've been told that ``killall -11 ppp'' or 
attaching to ppp with gdb just shows ppp in select() (as expected), 
but it may be worth confirming this too.

I can only guess that the problem is due to netgraph mis-processing 
some rogue data from the other side (data I can't reproduce here 'cos 
I'm using netgraph).  To this end, it may even be worth running 
tcpdump permanently on the link (with -x) so that we can get a look 
at the dodgy data.
