The module from head "works" for me with an 8120 on 9.1 stable (r247893) though the results are inconsistent. I am not certain of how useful they are. # sysctl hw.model hw.model: AMD FX(tm)-8120 Eight-Core Processor # kldstat | grep amd 5 1 0xffffffff8183e000 1043 amdtemp.ko # sysctl -a | grep 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: 47.7C Here are results taken at 0.1 second intervals using a shell script: dev.amdtemp.0.core0.sensor0: 42.1C dev.amdtemp.0.core0.sensor0: 42.2C dev.amdtemp.0.core0.sensor0: 42.0C dev.amdtemp.0.core0.sensor0: 42.1C dev.amdtemp.0.core0.sensor0: 41.8C dev.amdtemp.0.core0.sensor0: 41.7C dev.amdtemp.0.core0.sensor0: 51.1C dev.amdtemp.0.core0.sensor0: 51.0C dev.amdtemp.0.core0.sensor0: 50.7C dev.amdtemp.0.core0.sensor0: 50.5C dev.amdtemp.0.core0.sensor0: 50.1C dev.amdtemp.0.core0.sensor0: 49.8C dev.amdtemp.0.core0.sensor0: 49.5C dev.amdtemp.0.core0.sensor0: 49.2C dev.amdtemp.0.core0.sensor0: 49.2C and again: dev.amdtemp.0.core0.sensor0: 41.5C dev.amdtemp.0.core0.sensor0: 41.2C dev.amdtemp.0.core0.sensor0: 40.8C dev.amdtemp.0.core0.sensor0: 40.8C dev.amdtemp.0.core0.sensor0: 41.0C dev.amdtemp.0.core0.sensor0: 41.3C dev.amdtemp.0.core0.sensor0: 41.6C dev.amdtemp.0.core0.sensor0: 41.3C dev.amdtemp.0.core0.sensor0: 54.0C dev.amdtemp.0.core0.sensor0: 53.7C dev.amdtemp.0.core0.sensor0: 53.3C dev.amdtemp.0.core0.sensor0: 53.1C dev.amdtemp.0.core0.sensor0: 52.7C dev.amdtemp.0.core0.sensor0: 52.3C dev.amdtemp.0.core0.sensor0: 52.1C dev.amdtemp.0.core0.sensor0: 51.7C dev.amdtemp.0.core0.sensor0: 51.5C You can see during each series there are sudden increases of over 9C and almost 13C respectively.
