   No ideas, but I get exactly the same thing under similar
circumstances. At the moment I'm running with -current userland
and a 1.1 kernel, which seems to work for the most part except
that "systat -net" displays some signed integer where it should
have the connection state. I can reliably get pppd to hang by
running trn (downloads the active file) immediately after
connecting. I'd guess we're looking at a packet or byte count
as the trigger, though it could be higher traffic.
