Thanks for pointing that out! I have these commented on my loader.conf but I didn't know they were active somewhere else. As far as cpufreq/powerd goes, it's working now and frequencies are being throttled but still no cool'n'quiet/hwpstate0 showing on dmesg. acpi_throttle attaches to cpu0 but not to the others. acpi_throttle0: <ACPI CPU Throttling> on cpu0 acpi_throttle1: <ACPI CPU Throttling> on cpu1 acpi_throttle1: failed to attach P_CNT device_attach: acpi_throttle1 attach returned 6 acpi_throttle2: <ACPI CPU Throttling> on cpu2 acpi_throttle2: failed to attach P_CNT device_attach: acpi_throttle2 attach returned 6 acpi_throttle3: <ACPI CPU Throttling> on cpu3 acpi_throttle3: failed to attach P_CNT device_attach: acpi_throttle3 attach returned 6 acpi_throttle4: <ACPI CPU Throttling> on cpu4 acpi_throttle4: failed to attach P_CNT device_attach: acpi_throttle4 attach returned 6 acpi_throttle5: <ACPI CPU Throttling> on cpu5 acpi_throttle5: failed to attach P_CNT device_attach: acpi_throttle5 attach returned 6 acpi_throttle6: <ACPI CPU Throttling> on cpu6 acpi_throttle6: failed to attach P_CNT device_attach: acpi_throttle6 attach returned 6 acpi_throttle7: <ACPI CPU Throttling> on cpu7 acpi_throttle7: failed to attach P_CNT device_attach: acpi_throttle7 attach returned 6 sysctl -a | grep freq dev.cpufreq.0.%parent: cpu0 dev.cpufreq.0.%pnpinfo: dev.cpufreq.0.%location: dev.cpufreq.0.%driver: cpufreq dev.cpufreq.0.%desc: dev.cpufreq.%parent: dev.acpi_throttle.0.freq_settings: 10000/-1 8750/-1 7500/-1 6250/-1 5000/-1 3750/-1 2500/-1 1250/-1 dev.cpu.0.freq_levels: 3214/-1 2812/-1 2410/-1 2008/-1 1607/-1 1205/-1 803/-1 dev.cpu.0.freq: 803 Thanks again! -- Mario Lobo http://www.mallavoodoo.com.br FreeBSD since 2.2.8 [not Pro-Audio....
