I am having problem with my network manager in Fedora 19 with kernel version 3.11.2-201.fc19.x86_64.
To be precise, 'Modem Manager-0.6.2.0-1.fc19' is getting killed by signal 11.
It is sometime working, sometime failing to start i.e mobile broadband and wireless option is missing from Network Manager.Though wireless mobile broadband is being showed in nm-connection-editor, I can edit the connection profiles, but its going missing from network manager applet. Wired option and network settings in the applet remain as it is.
I have tried to figure out is there any kind of driver issue, so therefore did the following :
# lsusb is giving this output -> Bus 002 Device 004: ID 12d1:140c Huawei Technologies Co., Ltd. E180v.
# usb-devices is giving this output ->

Any kind of help will be appreciated. Thanks in advance.
