Edit: Title should be /proc/last_kmsg but my phone autocorrected.

Good Afternoon Everyone!

I am running the latest weekly of the Dirty Unicorns ROM and am getting some random reboots.

This only occurs while watching YouTube videos. The video will freeze and the device reboots. I wanted to pull a last_kmsg however it says the file doesn't exist.

Is there a new way to pull it in lollipop, or a new way to get the log for reboots?

Thanks for the help!
