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
