I am using user-mode ppp with pppoe.
It had been running on a DEC based board (de driver) for a few months
without trouble.
Yesterday I changed the board for a 3COM 3C905B-TX -> crash
I then cvsupped the system to 4.3beta (March 16), no change, the machine
now reliably crashes each time ppp starts.
Here follow the gdb backtrace and the boot messages, which I hope will
make sense for someone.
I can perform more testing or gdb incantations if something else is needed.
Regards,
J.F. Dockes
