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

OK, dropped from the list of recent regressions.
