Thanks for the clarification on Alain's suggestion. I ran the test and
it immediately failed. To make sure I was doing things right, I tried in
on another machine (which worked) and am trying it on a third machine
(which I will check in on tomorrow morning)..
Though I am not seeing any problems running on the machine that reported
the error during yum update, I am figuring "I gotta hardware problem". I
am attaching a file of my transciption of the error with the hopes of
getting some confirmation / education / advice / sympathy / etc.
Thanks for the help in teaching me where the testing stuff is on Fedora,
Paul
