hi, Linus Walleij,
we noticed this is a debug patch and lots of pr_info() are added, however,
we don't know below issue we captured in our tests is expected or if it could
supply any hint. so still report to you FYI.
if you don't want us to test this 'test' branch any longer, please let us know.
Thanks!
