View Full Version : [ubuntu] 14.04 - Incorrect CPU temp on AMD A10-7850 [Kaveri] after HWE install

February 24th, 2015, 07:10 AM
Hi everyone,

As the title says, my machine has an AMD A10-7850K APU which runs very nicely.

I installed 14.04 when it was released, however it launched with the 3.13 kernel which did not have official support for Kaveri APUs. In particular, the CPU temperature reported was incorrect [It would read around 0 degrees at idle, then maybe 20 under load.
Regardless, after my upgrade to 14.04.2 I decided to install the utopic HWE, which now sees me running 3.16 kernel, which DOES have support for Kaveri APUs. However, the CPU temperature appears to be the same as before. 0 degrees at idle, 20 under load.

I'm using lm-sensors to get the values. Running sensors-detect again actually results in it saying it cannot find any temperature probes at all. Something odd is going on.
Is there a kernel module I have to load to enable Kaveri support to the K10temp implementation?

Any assistance would be greatly appreciated.
