[Bug 27233] CPU temperature always reported as 22

[Trouilliez vincent]

Public bug reported:

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: Medium
     Assignee: Ben Collins
         Status: Unconfirmed


Description:
To read the temperature of the CPU, I read this file:
/proc/acpi/thermal_zone/THRM/temperature.
That worked perfectly with Hoary.
However with Breezy, things deteriorated... the file would contain "22",
regardless of the actual CPU temp. It would always read 22, go figure.
Now with Dapper, it's even worse... it doesn't report "22", it reports ...
nothing at all ! Yep, the file is empty, aaaaabsolutely..... empty. :-/

I have an old "nForce" motherboard with an Athlon CPU. I have to use the
"athcool" package (universe), in order to significantly lower the temp of the
CPU when it's idling (most of the time ie), and checking this "temperature" file
is the only way I had to actually monitor the CPU temp to make sure that
"athcool" does it job and that the CPU isn't overheating. So I kinda need this
thing to work !
I will do anything you want to troubleshoot it, just ask, and I will do it...

Do you want me to attach the output of "dmidecode" for more info, would that
help ? Some other command ??
