Bug#697548: linux-image-3.7-trunk-amd64: temperatures are too high on Lenevo T420

2013-01-06 Thread gpe
Package: src:linux
Version: 3.7.1-1~experimental.2
Severity: normal

Dear Maintainer,

   * What led up to the situation?

   updating with kernel 3.7.1. My machine is a Lenovo T420 (model
   4180AT9)

   * What exactly did you do (or not do) that was effective (or
 ineffective)?

 starting the system and logging into gnome session

   * What was the outcome of this action?

   sensors reports temperatures for cores and thermal zone which are
   between 52°C and 60°C

   * What outcome did you expect instead?

   when running with kernel 3.6.9 the temperatures are under 42°C

Regards.

Did you test this immediately after rebooting?  I would expect an
upgrade and reboot to make the CPU heat up.  You would have to leave it
idle for some minutes to make a proper comparison.

If the temperature really stays higher with the newer kernel version
then please install linux-tools-3.7 and generate a performance report:

# running as root:
perf record -g -a sleep 60
perf report -g  perf.txt

Then send the report file perf.txt.  (This report will list most
commands running on the system, so you may wish to remove any sensitive
information first.)

Ben.

In absolute not but for an idle state ...

Yes it's that I've done. I've switched several between 3.6.9 and 3.7.1 and
each the temperatures are significantly higher with 3.7.1.

 
 If the temperature really stays higher with the newer kernel version
 then please install linux-tools-3.7 and generate a performance report:
 
 # running as root:
 perf record -g -a sleep 60
 perf report -g  perf.txt

Could you confirm the last command please ?

Regards.
