Hm, no, I didn't.  I received an email from Justin Bronder but not from
Jaret Cantu.  Justin's email did help but is still pretty high-level.
We need a clear understanding as to what is happening in the digital
layer and the driver to know how execution is getting into a block of
error handling code that should never be executed.  Once we understand
that we can start thinking about what the best fix is.

I expect that it would help if he joins.  After the holidays is fine -
I think many people are taking it easy for the next week or so, anyway.

I think it would help you if you split it off because the first two patches
have a good chance of being accepted but this one doesn't (yet).  If you
separate the them, it will make it easier for Samuel to take the first two
(or he may take the first two anyway but its always good to make it as
easy maintainers as you can).
