[issue1162] fix for extrem notebook heat build-up

[Martin Kielhorn]

New submission from Martin Kielhorn <kielhorn.martin at googlemail.com>:

hi,
i really like grml. the grml system is much more responsive then my
harddrive based debian when loaded into ram.
it was quite easy to add emacs, slime and sbcl. now i have a very
productive common lisp development environment.

big thanks for this.


however i struggled with the problem of sever heat build-up for a few days.
the notebook gets a lot hotter than in debian 6 64bit.

i tried a lot of settings with powertop and finally came to the conclusion
that the following commands help:

sudo modprobe msr
root at shaitan ...tools/power/x86/x86_energy_perf_policy #
./x86_energy_perf_policy -v 'powersave'

in order to get this program, i had to "apt-get install linux-source-3.1"
and unpack the source in /usr/src

maybe other people would like to know about this as well.

regards, martin
