That's not answering my question - I'm asking you what steps you've
taken to progress, to explain the analysis you've done so far.  For
example, what is the blocked thread blocked on - what is it waiting for
and why has that thing happened?

If you have not addressed the review issues with your driver then take a
look at those, perhaps the problem has already been identified through
code review.
