Bug Description
Whenever I wake my computer from a "Suspend", System Monitor shows over 80 instances of kworker spontaneously get spawned. If I move the mouse, the PC crashes and I must restart.
If I don't touch the mouse and let the PC sit untouched for about 10 minutes, the 80 extra kworker daemons terminate and only the "normal" 8 remain. The PC operates fine from then on.
I get similar behaviour on 3 different machines, all 64 bit 16.04LTS.
