Not sure how to find out, but I did not change anything in the BIOS = settings (if even possible) or through sysctl regarding cpu idle modes. = Anyway, here's what I found: # sysctl machdep.idle machdep.idle_available machdep.idle: amdc1e machdep.idle_available: spin, amdc1e, hlt, acpi,=20 Not sure if "amdc1e" qualifies for something "other than C1". I tried = "hlt" once, which didn't make a difference IIRC. And if that's not what = you needed, here's more: # sysctl dev.cpu dev.cpu.0.%desc: ACPI CPU dev.cpu.0.%driver: cpu dev.cpu.0.%location: handle=3D\_PR_.P001 dev.cpu.0.%pnpinfo: _HID=3Dnone _UID=3D0 dev.cpu.0.%parent: acpi0 dev.cpu.0.freq: 2786 dev.cpu.0.freq_levels: 2786/95000 2587/81800 2388/69811 2189/58977 = 1990/49240 1791/44316 995/22525 dev.cpu.0.cx_supported: C1/0 dev.cpu.0.cx_lowest: C1 dev.cpu.0.cx_usage: 100.00% last 500us dev.cpu.1.%desc: ACPI CPU dev.cpu.1.%driver: cpu dev.cpu.1.%location: handle=3D\_PR_.P002 dev.cpu.1.%pnpinfo: _HID=3Dnone _UID=3D0 dev.cpu.1.%parent: acpi0 dev.cpu.1.cx_supported: C1/0 dev.cpu.1.cx_lowest: C1 dev.cpu.1.cx_usage: 100.00% last 500us dev.cpu.2.%desc: ACPI CPU dev.cpu.2.%driver: cpu dev.cpu.2.%location: handle=3D\_PR_.P003 dev.cpu.2.%pnpinfo: _HID=3Dnone _UID=3D0 dev.cpu.2.%parent: acpi0 dev.cpu.2.cx_supported: C1/0 dev.cpu.2.cx_lowest: C1 dev.cpu.2.cx_usage: 100.00% last 500us dev.cpu.3.%desc: ACPI CPU dev.cpu.3.%driver: cpu dev.cpu.3.%location: handle=3D\_PR_.P004 dev.cpu.3.%pnpinfo: _HID=3Dnone _UID=3D0 dev.cpu.3.%parent: acpi0 dev.cpu.3.cx_supported: C1/0 dev.cpu.3.cx_lowest: C1 dev.cpu.3.cx_usage: 100.00% last 500us Markus=
