Description of problem:

My Sierra Wireless modems (312U & 320U) not working.

Version-Release number of selected component (if applicable):

v3.10 kernel versions

How reproducible:

Always

Steps to Reproduce:
1.
2.
3.

Actual results:

ifconfig shows wwan0 not running;

"wwan0: flags=4227<UP,BROADCAST,NOARP,MULTICAST> mtu 1500"

Expected results:

"wwan0: flags=4291<UP,BROADCAST,RUNNING,NOARP,MULTICAST> mtu 1500"

Additional info:

I've found the fix is to "make" and "make install" the v3.9 kernel driver files "sierra.c" and "sierra_net.c" from http://lxr.free-electrons.com/source/

In fact, it's only "sierra_net.c" that seems to be implicated. For more detailed info, please see: http://forums.whirlpool.net.au/forum-replies.cfm?t=2135188&p=14#r275
