I haven't posted the following as a bug yet, but when I ssh into the unit as 
root I get an oops as shown in the attached file.  But if I ssh into the unit 
as a normal user, there is no oops.  The oops is non-fatal, as far as I can 
tell, but unsettling regardless.

The above is misleading.  Turns out the oops is generated by doing:

        kbdrate -d 500

which I had added to my .bash_profile.  That command opens /dev/port, which 
only root can do.  So a normal user cannot trigger the oops but the root user 
can.

I opened bug https://bugzilla.redhat.com/show_bug.cgi?id=2108633 because while 
root can certainly crash a system in many ways, the kbdrate command really 
shouldn't cause an oops.
