I have a Moto G 4g (peregrine XT1039), which in every one or two days reboots to bootloader with "Fastboot reason: failed to initialize partition table", see Image(1).
In Image(2), you can also see "Device is LOCKED" on the photo, but I've unlocked it as you can see when I rebooted to bootloader manually.

I was using CM12 but tried to solve this by flashing a stock image following this thread. I also tried to solve this by replacing battery with a new one, but it didn't help. I think my device is defective, but I lost my warranty unlocking it and replacing battery.
Does someone know how to get rid of these reboots?
