[Bug 1580313] [NEW] Plasma freezes on 16.04

 

Public bug reported:

Every once in a while, maybe 4-5 times a day at work, my fresh install
of 16.04 Kubuntu freezes and I can't click on anything whatsoever. I
need to reboot every time.

The keyboard still works though, as I was able to start a new session.
At login screen, the following message kept showing up every 5 seconds :

FIFO:SCHED_ERROR 0a [ctwsw_timeout]

Some info on my system
