ACK, if someone has the same problem he can just work around it
using the information and steps you provided in this bug report.
Thanks!

This works fine. I just tried it.
I just had to do
sudo apt-get install linux-headers-3.10-1-grml-all build-essential

I had a look at the code of the module but I don't understand it well
enough to say if its possible to replace it with a script in userlevel.
Also, I think this is just to dangerous to put on live CD.

You could try grabbing a Grml ISO, making sure that the according
linux-headers package is installed (like
linux-headers-3.10-1-grml-all for 2013.09-rc1) and then install
bbswitch-dkms to see whether building, installing and using this
kernel module works.

(I'm afraid we don't have a sane mechanism to ship it via Grml
by default though.)

hi,
i have news with regards to this overheating bug.

i tried loading the module https://github.com/Bumblebee-Project/bbswitch

this way i can disable the discrete nvidia graphics card and it seems to
prevent the heat problem.

i understand this issues some acpi commands that disables the discrete
nvidia graphics.
however, i'm not sure how save this would be to provide with grml.

my notebook is an Acer TravelMate 5760G with a nvidia geforce GT 540M as
discrete graphics card.

regards, martin

Marking this bug as "dead" because there was no feedback/update for ~7 weeks.
Feel free to reopen the bug if you think there's a way how we could improve Grml 
to resolve your issue.

Mika

Hi Martin,

could you test this with a current daily.grml.org ISO (which provide new kernel 
3.6.10) and report back whether you still have any problems with it? Unless I'm 
mistaken I don't see any real option to fix this issue within the Grml system.

regards,
Mika

To: GRML issue tracker <bts@bts.grml.org>


I was jumping to conclusions.
The problem is seems to be related to pcie_aspm.

Without change powertop (version 1.11) reports 40W power consumption
and the following is reported as a policy
~ % cat /sys/module/pcie_aspm/parameters/policy
[default] performance powersave


I added pcie_aspm=force to the kernel boot parameters and have 24.6W power
consumption (which I think is normal for this notebook). The policy is then
reported as:

~ % cat /sys/module/pcie_aspm/parameters/policy
default performance [powersave]

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@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
