Bug Description

Running kernel:

Linux XXX 2.6.32-25-generic #44-Ubuntu SMP Fri Sep 17 20:26:08 UTC 2010 i686 GNU/Linux

on Acer Aspire One D250 with Intel Atom CPU.

sensors version 3.1.2 with libsensors version 3.1.2

$sensors

coretemp-isa-0000
Adapter: ISA adapter
Core 0: +44.0°C (crit = +90.0°C)

With the PREVIOUS kernel (2.6.32-24-generic), TWO temperatures were output, one for each core. Have run sensors-detect a few times and restarted, etc. but did not solve the problem.

Exact problem noted on Gentoo forum:

http://forums.gentoo.org/viewtopic-t-846162.html?sid=40f53a36937c24504d2f18418ee37a54

and a "workaround" to fix it was to downgrade kernel.

Hi SabreWolfy,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily/current/ . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 653499

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Sorry, I'm not interested in testing development/upstream kernels. I detailed in my first post that the feature worked in kernel X and stopped working in the next kernel. I'm intentionally running 10.04 *LTS* on all my machines to avoid fiddling around with testing kernels and development builds. I'm not in a position to download massive daily ISO files and do fresh installs to test. Sorry. Imagine if I was a "mom and pop" user and received the above instructions?! Thankfully I'm not, but I still don't have time or bandwidth for this. Sorry.
