My Moto X (2013, Dev Edition on VZW, 5.1 L w/ Xposed and root and unlocked BL) seem to spontaneous reboot a couple times a day, doing different things, usually Bluetooth is on while I'm doing something else, but can't find any other common factors. Sometimes I'm just checking Google Now topics, sometimes I'm checking links in Chrome (but also happens with Dolphin)

I searched XDA and it says to check out last_kmsg which I got, but it's rather... dense? But there seems to be no kernel error. The log mainly contains "wlan:" notes, until it reaches the following:

So for 6 seconds WiFi went blank, which caused OS to panic and reboot? I'm a little confused. Where do I go and what do I read to figure out what's my phone's problem? :)

Greetings,

As a senior member of this site, with a device that has a dedicated forum, you are expected to know how to find your way. XDA Assist is for new members who need help finding their way, it is not a help desk for troubleshooting issues. Please re-read the sticky threads for this forum so you have a better understanding of what we do here.
