I don't think the problems are related as the oops seems related to
the isdn_tty specific code that is not touched at all by the isdn_net code.
My impression is that the net problems are isdn_ppp specific. At least
I havn't seens any similar report with raw-ip encapsulation.
I also detected another race condition in the isdn_ppp code that might be
responsible for the occasionally observed tcp stalls.
As regards the isdn_ppp stalls? Recently, I observed such a stall myself.
A ping running while the bad-performing tcp connection was active reported
several duplicated packets. Did anybody observe similar things during the
stall?
