This happens to me about three times a week on Ubuntu 18.04.3 LTS with kernel 4.15.0-70-generic. I have not been able to find a way to consistently reproduce it. It is a random complete system freeze. The mouse does not respond, caps lock and numlock do not change light on keyboard, ctrl alt f2/f3/etc does not work, and even Alt + SysRq REISUB does not respond. Only a hard reset works by pressing the power button will reboot the system. The first sign of it happening is the mouse begins to stutter for a couple seconds before the whole screen completely freezes. Here is some system info:
