I rebuilt my 4.2-RELEASE kernel that has been in use for ages
with the following extra lines in the config:
options NETGRAPH #netgraph(4) system
options NETGRAPH_PPPOE
My earlier attempt to run ppp(8) on my new ADSL modem failed
because netgraph was not in the kernel.
After building a clean new kernel and installing it with the new
modules, I tried ppp again and got a panic after a few seconds.
I've tried it about six times. Most attempts got a panic (and I
have typed up the console screen from one of them below), but
some just skipped the panic and rebooted.
On some attempts, we got a little bit of logging from the ppp
process. Here's one such log:
------------------------------------------------------------------------

Each line also had the following data after the date:

Here's the console screen on one panic:

If anybody can point me in the right direction to solve this,
I'll be very grateful. My sole goal is to get ppp to talk to my
ADSL modem, so if there's some other magic I should try, I'm
happy to do that.
