Mark, can you still take these changes first? Since this failed
test that Caleb reported here is already existing on the top of
the mainline tree, I would like to treat this mail as a separate
bug report and fix it with a separate patch.

Besides, this series of changes don't change any function flow.

Thank you

I really appreciate your verification and help.

I remember Arnaud reviewed one of my changes back to September.
So I suppose the test should be fine at that time -- so a change
being merged recently might have impacted the test result.

I would definitely like to take the hardware to debug it as long
as you are willing to provide me. Can you send me a private mail
to discuss about it?

Thanks
