I believe you have hardware problems:

[ 5735.628897] [Hardware Error]: Machine check events logged

[ 6103.053770] CPU1: Core temperature/speed normal

[ 6141.037069] [Hardware Error]: Machine check events logged

First make sure your CPU fans, heatsinks, etc., aren't clogged with
dust. Then check if your heatsink is properly adhered to your CPU -- too
much or too little thermal paste can both be problems.

Good luck.
