    I was never able to determine where (or how) the controller was getting
    Someone had posted a message about something very similar, where they
 were getting the controller halted, and had proposed a fix to restart
 the controller when it detected a halt.  I don't think I ever saw a 
 response to that message, and nothing more was done with it.  I was always 
 going to try to see if that change help on the Optiplex 745, but never 
 think about it when I'm updating that machine.  I don't recall at the 
 moment who posted that message, or what list it was on.  I should still 
 have it, so I'll try to dig it out.
