Similar thing here at home desktop running -CURRENT: CPU: AMD FX(tm)-8350 Eight-Core Processor (4000.24-MHz K8-class CPU) Origin="AuthenticAMD" Id=0x600f20 Family=0x15 Model=0x2 Stepping=0 acpi0: <7596MS A7596100> on motherboard Other related bits: # sysctl hw.acpi hw.acpi.supported_sleep_state: S3 S4 S5 hw.acpi.power_button_state: S5 hw.acpi.sleep_button_state: S3 hw.acpi.lid_switch_state: NONE hw.acpi.standby_state: NONE hw.acpi.suspend_state: S3 hw.acpi.sleep_delay: 1 hw.acpi.s4bios: 0 hw.acpi.verbose: 0 hw.acpi.disable_on_reboot: 0 hw.acpi.handle_reboot: 0 hw.acpi.reset_video: 0 hw.acpi.cpu.cx_lowest: C8 # # sysctl dev.amdtemp dev.amdtemp.0.%desc: AMD CPU On-Die Thermal Sensors dev.amdtemp.0.%driver: amdtemp dev.amdtemp.0.%parent: hostb4 dev.amdtemp.0.sensor_offset: 0 dev.amdtemp.0.core0.sensor0: 15.3C # sysctl -a dev.cpu | grep temp dev.cpu.0.temperature: 15.2C dev.cpu.1.temperature: 15.2C dev.cpu.2.temperature: 15.2C dev.cpu.3.temperature: 15.2C dev.cpu.4.temperature: 15.2C dev.cpu.5.temperature: 15.2C dev.cpu.6.temperature: 15.2C dev.cpu.7.temperature: 15.2C I am not sure how this ^ relates to what acpi reports under thermal.
