Comment 16 for bug 990337

Kindly let me know when this will be available as an update.
Also I have now seeing that the connection is getting dropped after being online for 50 min to an hour and the modem disappears from the network manager. I can get the connection back by pulling out and then plugging it back in. But again it will go after 50 min.

Pasting the last few entries from dmesg below.
