Could you do me a favour and execute "sysctl dev.cpu.0". It seems that the frequency levels are not handled correctly yet. Here's my output: ============================================================================== #sysctl dev.cpu.0 dev.cpu.0.cx_method: C1/hlt C2/io dev.cpu.0.cx_usage_counters: 16616204 0 dev.cpu.0.cx_usage: 100.00% 0.00% last 375us dev.cpu.0.cx_lowest: C1 dev.cpu.0.cx_supported: C1/1/0 C2/2/400 dev.cpu.0.freq_levels: 3400/3562 2700/2835 1550/1312 dev.cpu.0.freq: 2700 dev.cpu.0.%parent: acpi0 dev.cpu.0.%pnpinfo: _HID=none _UID=0 dev.cpu.0.%location: handle=\_PR_.P000 dev.cpu.0.%driver: cpu dev.cpu.0.%desc: ACPI CPU #sysctl dev.cpu.0.freq=3400 dev.cpu.0.freq: 2700 sysctl: dev.cpu.0.freq=3400: Device not configured #dmesg -a | grep hwpstate hwpstate0: <Cool`n'Quiet 2.0> on cpu0 hwpstate0: set freq failed, err 6 ============================================================================== TIA and regards, Nils
