Okay, fine.

So Original Poster, OP, has all what is needed to some solve an interresting 
problem.
* the problem itself
* most likely an incentive to solve the problem
* working configurations
* a non working configuration
* source code and build tools for one end of the non working configuration
and hopefully full access at the other end of the non working configuration


I wonder what the reason is for the posting of the OP.

@OP  please elaborate
