While dialing up to my ISP, /var/log/messages contains this modprobe
message after 'local' and 'remote' IP addresses are listed. Does it come
from pppd? modprobe /dev/ttyS0 is obviously senseless.
Have you modified your kernel since you installed?
No. I haven't checked to see if this bug is still present. I'll try again
tonight if I get time.
This got fixed already I think.
