Thanks for the suggestions.


Given the motherboard is circa 2011, Debian 9 has reached end of 
maintenance, and the lack of response on my initial bug report, I doubt 
this bug will be fixed.  Even if I had some success in debugging the 
issue and submitted reports and/or patches, I don't know if or what the 
Debian project would do with them.


It's time to put in a fresh system drive and try something newer that is 
actively supported.
