317	High power consumption with /SMP /APIC with Nvidia + SMP Kernel	mobybrick		"Hi,

Thanks for your efforts on ACPI!

I have tested two new NVIDIA based systems (one mine, one a colleage). One has an Athlon dual core, the other a single core.

When using eCS RC5, both systems works fine on UNI processor with ACPI 3.09/11.

When switch to SMP kernel and /SMP /APIC, both systems (one single HT core, one dual core) greatly increase their power usage and slowly overheat. With the SMP kernel, the systems use nearly 40 watts more power - even though one of them is still running on just once CPU core.

SetGetThtrl reports states of 0x0 available for throttling. Attached is acpi.log.

Seems to be the SMP kernel ? I think I read about some HLT states? Or is it how it reacts with ACPI.PSD?

Thanks for any suggestions. Am willing and able to try anything you need."	enhancement	closed	major	Feedback pending	ACPI PSD	3.14	unknown		mobybrick
