Re: Null pointer dereference - 1.3.10/pppd

Hep. Even when the file transfer is the only active user, ppd crashed at
the same spot as in the first message that I sent. I then tried to boot with
1.2.10, but I got another crash. This happens always after transferring
~150k. Maybe there's a limit at the receiving side - will try to find out,
but this should not cause null references...

I am including the messages from the 1.2.10 kernel, but I cannot add the
procedure references, because I don't have the system map for it
anymore (not even the sources - lack of disk space). Hope this is of some
help. It appears as if this is the same error...
