[LG Optimus G (International)] virusxr866:
I have same issues with my LGE-975, EU version.

This can happen once per month. Or 10 times a day :(

It's clean install, did it two times just to be sure. Updated baseband from 10b to 10d. So now it's

LGE975AT-00-V10d-EUR-XX-APR-01-2013+0

CM 10.1.2-e975

kernel 3.4.0-CM+ build02@cyanogenmod #1 Thu Jul 11 18:03:45 PDT 2013

buildnumber cm_e975-userbug 4.2.2 JDQ39E

eng.jenkins.20130711.175036 test-keys

The only trace in logs seems to be this (from last_kmsg):
