You're not seeing any of this? | OS X: When your computer spontaneously restarts... https://support.apple.com/en-us/HT200553 Kernel panics are not easy to interpret. Generally you'll need a second machine - https://developer.apple.com/library/mac/technotes/tn2004/tn2118.html If you're not getting any panic data logged, you can try dumping them directly to the screen - sudo nvram boot-args="debug=0x0100" But, these data may not be very useful on their own. Other than perhaps to send a photo of them to Apple, heh. And, some OSX versions will do this simply from booting in the verbose mode, but I can't recall which ones.
