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.
