Your core problem (heh) is caused by the fact that the idle behavior of the uniprocessor kernel is to halt, waiting for an interrupt. The idle behavior of the SMP kernel is to loop, looking for work to dispatch. This means the SMP never halts, and therefore runs hotter. That doesn't give you a cure, however... :-( -crl -- Chad R.
