Although I believe there might be a bug upstream for this, if you are using an amd board, mostly the socket 939 boards, you need to add this to your kernel line to allow lm sensors to report values. acpi_enforce_resources=lax Reproducible: Always
I advice you to exercise caution with acpi_enforce_resources. I'd also like you to read these: http://lists.lm-sensors.org/pipermail/lm-sensors/2009-January/025063.html https://bugzilla.redhat.com/show_bug.cgi?id=494938#c5 Also, could you attach the output of your: 'lspci -vvv' and 'dmesg'? acpi_enforce_resources=lax should be reporting collisions in your kernel log.
Created attachment 204357 [details] lspci vvv
Created attachment 204358 [details] dmesg
Seems that there is a conflict ACPI: I/O resource it87 [0xd05-0xd06] conflicts with ACPI region ECRE [0xd00-0xd1f]
Alright, I'll have to mark this bug as WONTFIX. I'd advise you to read the following: http://bugzilla.kernel.org/show_bug.cgi?id=13967 http://hansdegoede.livejournal.com/7932.html After reading these, it's up to you if you want to use 'lax' or 'no' in your acpi_enforce_recourses. Thanks for the bug report!

For anyone who runs into this, see here for using the acpi hardware driver instead. http://bugs.gentoo.org/show_bug.cgi?id=244598
