--- Comment #24 from Marta Löfstedt <marta.lofstedt at intel.com> ---
Zijstras "new" patchset does not produce clean results. I have tested both with
and without the tsc=unstable kernel boot parameter.

But, the failure rate has gone down significantly.

I have 14 tests and to 50 repetitions => 700 invocations

Before Zijlstra first patch, failure rate was approximately 50% => 350 fails
Ziljstra first patch-set => 30 fails
Ziljstra new patch-set => 15 fails + 1 dmesg-warn

So, this is a big improvment.

However, since Villes patchset appear to fix the problem by 100%, we don't need
the Zijlstra patches for solving this regression.
