[Galaxy Note 3 Android Development] ImaPseudonym:
I have tried this flashable SU on the 20170116 version, didn't work. Ended up just flashing the latest flashable zip from supersu.com, that worked fine.

Okay, so as suggested I installed LogCat, but didn't realize i would need to put it on record. So while I had one of these random reboots again today, it wasn't caught by LogCat. However, I did install a terminal emulator and dug up the last_kmsg. I've included the first 200-something lines here and can provide the rest if necessary (however, the full file is 1769 lines and I'm not sure whether there's any risk of privacy-sensitive stuff ending up in there)
