I experienced two reboots this week and others in past weeks.
The most recent, about 15 minutes ago, happened while I was logging into a website. I had four other tabs open, as well as a terminal window and keepass2. Nothing seemed out of the ordinary. My mouse and keyboard stopped working, the screen went black and rebooted.
I am running the stock OS and just updated with Mr. Fixit's script yesterday.
I'm guessing this is a kernel panic, but I have very little experience diagnosing this type of issue. Perhaps someone will chime in with some pointers.
I got a bunch of this in dmesg right before the latest reboot:
