Also there is no sysctl hw.acpi.cpu.px_dom0.select available,
so I guess powerd is also running not properly and the CPU frequency is not scaled in any way. After looking into the dmesg output, I guess some driver does not recognize parts of the hardware/ACPI stuff correctly (see below; the text is repeated for the other 3 logical CPUs). cpu0: on acpi0 cpu_cst0: on cpu0 cpu_pst0: Can't get _PSS package - AE_NOT_FOUND The dmesg is attached. It would be great if there is someone who can help me to get this fixed. If more details are
necessary, just let me know. Sven
