This means you are experiencing a modem firmware crash.

Also read Cisco 3G and 4G Serviceability Enhancement User Guide [1].

You definitely don't want to run this image, its a 3 year old build
from the early 15.1 days.

Upgrade to to the most recent rebuild of your train (15.1(4)M7) or
think about upgrading to 15.2(4)M5.


Also upgrade your HWIC-3G-HSPA-G firmware (which you need todo manually),
download here [2] and see the upgrade instructions [3].


I never had any issues after upgrading IOS and firmware code.



Regards,

Lukas
