    Same here, and I'm aware of some others having problems which have been
    reported via mail and usenet. Changing configs hasn't changed a thing,
    either with a minimum config or with all options at sensible or stupid
    values.

    ISTR the problem occurred 2.1.107-108. Symptoms are an apparent failure for one
    end to see the LCP negotiation from the other resulting in an LCP timeout.

    I've pulled down clean kernel and pppd sources (twice!) but with no
    change. SLIP still works. This is DEFINITELY 2.3.5 pppd:) The same configs
    work fine under 2.1.103. An example debug session is given below although
    I can't remember exactly which config was used.

    Note that I have got different debug messages but the same outcome when
    trying Ascend or USR kit at the ISP end.

    If anyone wants me to try anything, I'm all ears.
