Comment 96 for bug 418509

Odds are it was switched on during your installation and various things got
installed to support it. Even if the device is disabled, there is a
possibility it would still be "found" during installation and those network
things would get installed.

My guess is your hang on shutdown is being caused because you don't have your
built in 3G configured correctly (if that is even possible) and the network
shutdown is waiting for a response it never gets.

You need to close this bug.

Once you spend a lot of time in the networking forums looking for how to
correctly configure your built in 3G modem, you will either solve your problem
or you will find an existing bug report to attach your information to.
