    This bug is still present in 2.6.37-rc2, but (as the original reporter)
    I now doubt it should be classified as a regression. It looked as if
    it was a regression because in the 2.6.35 kernel (the first kernel to
    include intel idle), intel idle was available as a kernel module and
    that module never in fact loaded on my hardware and so never caused a
    hang. In 2.6.36 onwards, intel idle is only available directly compiled
    into the kernel and that is when the hang became apparent: subsequent
    testing shows that the hang also occurs with 2.6.35 if intel idle is
    compiled in rather than as a module.

    So it is a bug, which is still present, but not necessarily a
    regression.

    Chris
