[Bug 574910] Re: High load averages on Lucid while idling

[John Johansen]

Just to be clear,

The test kernel mentioned above fixes a bug with the way load is
calculated on the -EC2 kernels in Lucid.  The fix reverts a patch that
was applied to Lucid for a different load accounting bug for tickless
kernels.  However the -EC2 kernels are not tickless and as such the
accounting logic was broken.  The Lucid kernels, and the test kernels
have been tested extensively on different loads, and compared to the
Karmic kernel, and the test kernel fixes the load reporting as expected
but does not change any other behavior of the Lucid kernel.

The only reason to use the test kernel is for resolution of the phantom
load issue.  It does not address any other problems on Lucid.  Lucid is
a different kernel than Karmic and will have different performance
characteristics for some loads.  If you try the test kernel and are
experiencing performance regressions please open a separate bug.
