(Though, I guess ACPI is used for stuff other than power > savings.) Maybe acpi=off? a) Power Management is available on SMP, though support for it is a bit less wide-spread than it is for UP b) ACPI stands for Advanced _Configuration_ and Powermanagement Interface. For SMP and especially SMT (e.g. HyperThreading) on x86, it is essential for proper system set-up. Dominik
