Hello, I am getting impossibly low temperature readings on a new system running FreeBSD 10.0-STABLE #0 r268555 amd64: # sysctl -a | grep amdtemp dev.amdtemp.%parent: dev.amdtemp.0.%desc: AMD CPU On-Die Thermal Sensors dev.amdtemp.0.%driver: amdtemp dev.amdtemp.0.%location: dev.amdtemp.0.%pnpinfo: dev.amdtemp.0.%parent: hostb4 dev.amdtemp.0.sensor_offset: 0 dev.amdtemp.0.core0.sensor0: 17.2C dev.amdtemp.1.%desc: AMD CPU On-Die Thermal Sensors dev.amdtemp.1.%driver: amdtemp dev.amdtemp.1.%location: dev.amdtemp.1.%pnpinfo: dev.amdtemp.1.%parent: hostb10 dev.amdtemp.1.sensor_offset: 0 dev.amdtemp.1.core0.sensor0: 19.1C The BIOS only says CPU temp "Low". Smartctl shows 30C for hard drive temperatures. The ambient temp in the room is about 24C - defective CPU thermal sensors? -- Janos Dohanics
