Random Reboot (Last_kmsg attached)

I've been getting random reboots for a while now on this Oneplus One and I would like some help finding out the culprit. I run Temasek's CM12.1 ROM and have been getting this problem intermittently. It reboots when I do something sometimes or when my phone is just laying there.

The last_kmsg file is here:

If you could help, that'd be amazing. Thank you.
