ppp dialup problem


Hi,

My dial up on Redhead 8 has been working ok for more than a year but is now broken.
Couple of days ago I tried the command:
rmmod hcfpciserial hcfpcispec hcfpciengine
It failed and since then when I try to start pppd the modem driver
cnx..mdmthrf seems to be thrashing, using up to 40% of CPU time and
still runs for another five minutes after pppd dies, using up to 20%
of cpu time. A lsof on pppd and cnx..mdmthrf shows the following:
---------
==>sudo /usr/sbin/lsof -p 8341
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
pppd 8341 root cwd DIR 3,2 4096 2 /

Any idea what might be messed up? thanks
