Bug Description

Binary package hint: linux-source-2.6.20

On a core duo cpu, you can't access the cpu sensors using lm-sensors with a kernel < 2.6.22 unless you apply a kernel patch adding the coretemp module.

http://www.debianhelp.org/node/5156 has the patch and how to apply it. I've built a custom kernel, applied the patch, upgraded lm_sensors to 2.10.2, and now can access both cores temperature sensors directly.

Have you tried compiling the coretemp module source against the Ubuntu 2.6.20-generic headers or applying this patch to the Ubuntu kernel source? Easier than compiling and maintaining a homebrew kernel.

I didn't make myself clear, when I wrote I build a custom kernel, what I did was that I built a custom kernel from the ubuntu kernel source with this patch applied, using the debian tools.
I am right now running that kernel, and the patch is the only difference from the ubuntu 2.6.20.3 kernel sources.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

The coretemp sensor has been in the kernel since hardy (kernel >= 2.6.22 includes the module, as was written in the bug report).
