Hi,

I have tried to create the log, but at Point 7 there is no Message from
the gdb. I have added the log, as I got it.

root trymon-laptop:/home/trymon# stop network-manager
network-manager stop/waiting
root trymon-laptop:/home/trymon# killall -TERM modem-manager
root trymon-laptop:/home/trymon# gdb modem-manager
