I do care about it.  But since the second board works, I know it is not
a problem with the design.  My design is not crashing, a particular
implementation of the design is crashing.

I agree completely.  But this would have to be in my own time, which
means I'm not getting paid for it.  I'm already overtime on this project
(meaning I am getting paid less and less per hour) and my customer only
cares about getting working prototypes (these are research proofs of
concept, not commercial products).  Sometimes when you get crunched for
time, you are just happy to get something working.  In the back of your
mind you day "later, I need to go back and investigate that further."
Sometimes you do, sometimes you don't.

I actually do software professionally.  I am always happy when I find
something that doesn't work as expected, because it means that my mental
model is wrong.  That's where all the real learning occurs.

I will definitely investigate this one further, if for no other reason
than to completely close out this discussion.  Unfortunately, I am on
travel right now, so my tools are pretty limited.  :-)
