Bug Description

Description: Ubuntu 16.04.5 LTS
Release: 16.04

I'm experiencing random dekstop lockup, in particular when maxing out build jobs.
Sometimes, the desktop freeze for a moment but then it recovers and i was able to capture some dmesg output (see attached pics).
Others, it just solid freeze (and numlock + scroll lock lights on my keyboard blinks).
