I am not familiar with the A10 CPUs. Are those similar to K10 ?
If so, maybe the k10temp driver works or could be extended to support it.
Can you give it a try ?
If it does not work out of the box, can you send me the output of "lspci -nn" ?
Kapil: I believe K10 corresponds to A8 seried, and A10 has Bulldozer architecture (http://www.cpu-world.com/CPUs/Bulldozer/TYPE-A10-Series.html). I am not sure how different they are though. I tried K10, but it did not work out of the box. I am looking into k10temp.c driver now. Also,I am attaching the output of "lspci -nn" command herewith; you might have to open it using wordpad for proper formatting..

Kapil: When I used another sensors-detect (probably a newer one) script, I no longer see the above warning. It recommended me the following at the end of sensors-detect: "copy prog/init/lm_sensors.init to /etc/init.d/lm_sensors". I couldn't find the prog/init directory, but I copied /etc/sysconfig/lmsensors file in to /etc/init.d directory. But, I still have to insert the f71882fg.ko driver every time I restart the computer. I couldn't run "make install successfully, as suggested here: http://khali.linux-fr.org/devel/lm-sensors/drivers/INSTALL .
