The best way to help fix these problems are:
A) Submit a patch for the changes you made.
B) Contact the maintainers and provide them with all of the details,
what you found, what didn't work, what you modified and the final
results. If you have traces or data captures, they may want to see them.
They can't fix problems they don't understand. If they don't have access
to that hardware, or something similar, they might even ask you to do
some experiments for them to extend their knowledge. All of that will
help them improve the quality of future releases.
