the example posted shows cpu results that are not multiples of 100%, so we are not seeing quite the same thing here.

assuming ignorance is not the same as assuming someone is an idiot. When I first ran across the >100% cpu and inconsistant between different tools other people had known about it for years, but it looked like a bug to me, so I see no reason why other folks could not be in the same situation today.

But as I said, it's not at all surprising to see bugs in the scheduler's reporting of time with the NOHZ changes, I seem to remember that the article talking about them indicated that they were still working to nail down and fix bugs in the reporting side.
