Thank you, it really helps, now after boot I always get valid 1.7Ghz as high possible CPU speed. but sysctl picture changed: now I have: % sysctl dev.cpufreq dev.cpu dev.p4tcc dev.acpi_throttle dev.cpufreq.0.%driver: cpufreq dev.cpufreq.0.%parent: cpu0 dev.cpu.0.%desc: ACPI CPU dev.cpu.0.%driver: cpu dev.cpu.0.%location: handle=3D\_PR_.CPU0 dev.cpu.0.%pnpinfo: _HID=3Dnone _UID=3D0 dev.cpu.0.%parent: acpi0 dev.cpu.0.freq: 1487 dev.cpu.0.freq_levels: 1700/-1 1487/-1 1400/-1 1225/-1 1200/-1 1050/-1 1000= /-1 875/-1 800/-1 700/-1 600/-1 525/-1 450/-1 375/-1 300/-1 225/-1 150/-1 7= 5/-1 dev.p4tcc.0.%desc: CPU Frequency Thermal Control dev.p4tcc.0.%driver: p4tcc dev.p4tcc.0.%parent: cpu0 dev.p4tcc.0.freq_settings: 10000/-1 8750/-1 7500/-1 6250/-1 5000/-1 3750/-1= 2500/-1 1250/-1 sysctl: unknown oid 'dev.acpi_throttle' % so I've lost dev.acpi_throttle and got dev.p4tcc. Is it right ? powerd still works as expected. > Sincerely, --=20 Vladimir B. Grebenschikov SWsoft Inc. vova@swsoft.com
