(Or does the message at > 495.496032 mean that we turned it off?) Looks like mdm6600 either entered low-power mode, or hung? If it hung, it's internal watchdog might bring it back after a while. If it entered low-power mode, in theory we should see the state change interrupt that's handled by phy-mapphone-mdm6600.c. I never managed to do that so far so maybe you figured it out with some command.
