Description of problem: The problem is triggered (sometimes) when I use an external (DisplayPort) KVM-switch. The crash appears (I think) more frequently, if I switch when the display is on. I have taken to locking the screen before I switch over, as this appears to reduce the problem frequency. I experienced the crash (same symptoms, anyway) a few time with F28. After upgrading to F29 it happens daily.
