[Bug 710319] Re: CPU usage is incorrect on server-status page

[Stefan Bader]

@tinodj, were you using the test from the reply (the original test case
had a flaw)?

Anyway, the patch that Scot mentioned could be fixing things. But for
Lucid this was added in Ubuntu-2.6.32-25.44 and at least in the comment
a -24.43 kernel was used. So first question: is this still seen with a
2.6.32-28.55 kernel?

When browsing over patches I had the feeling there could be other things
falling into that area as well, for example

commit c28739375bf0d6e239b4fa939ec8372aa2c707d2

    cpu-timers: Avoid iterating over all threads in
fastpath_timer_check()

But I would first want to double check that it is the right test case
failing with the right kernel.
