It remains unclear why a double initialization of the port

Thanks!
Can you test patch from [1] if it helps and doesn't break anything in
your case?

On its own, this patch doesn't seem to cure the issue (and it
adds a compile-time warning due to unused flags).
Or did you mean to test it in complement of my patch?
