xserver restarting with certain usb events

[Clyde E. Kunkel]

In current rawhide on one of my test systems (actual hardware, not 
virtual machine) when I unplug/replug the usb mouse/keyboard (they are 
on a kvm switch) the xserver restarts.  This started about a month ago 
right after the rebuild of the X stack packages (not saying that is the 
culprit, just the only timeframe I can reference).

I don't know if this is xorg-x11-drv-evdev, Xserver, systemd or what. 
  Any help in pinpointing would be appreciated so I can bz.  Does not 
occur on same machine with F16, 15 or 14.

This is a radeon HD2600 card running standard ati driver.

Xorg.0.log.old shows this activity after switching:
