Public bug reported:
My Sierra 308 Mobile broadband used to connect to Ubuntu 10.10 without
any problems, then one day it suddenly stopped working. The device
connects fine in Windows so it is not a hardware problem. I have tried
reinstalling Ubuntu, and both downgraded and upgrading the packages but
nothing seems to work. It seems to be connecting fine then for some
reason it suddenly stops. Below is the output from modem-manager and
Network Manager in debug modes.
