I've been trying to anything useful after the SMAP printed out, and have
failed.  I assume that because of the place where the system is throwing
a panic.  

Here is the SMAP output, I had to capture it twice to get it all on the

Immediately after, it jumps into the panic.  I assume that this means
more to you folks than it means to me.  I'm still working on the printf.
