Default Bug#615871: linux-2.6: CPU temperature very high Toshiba A200 Intel Dual Core

Would you be willing to bisect?

Like so:

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
cd linux-2.6
make localmodconfig

git bisect start
git bisect good v2.6.32
git bisect bad v2.6.37
make -j2 deb-pkg
... wait for it to build, install the resulting package, reboot ...

git bisect good; # if it worked okay, or
git bisect bad; # if it overheated, or
git bisect skip; # if an unrelated problem made it difficult to test

make -j2 deb-pkg
... and so on

Once we know which is the first bad commit, this should be much easier
to track down.

Thanks!
Jonathan

Don't bother, you'll just find the change which corrected temperature
decoding.

Thanks, Ben. Do you have any advice for a person finding that
graphics-intensive activity causes the machine to overheat?

I suppose this is more of a question for debian-user now.

OK, then try bisecting as Jonathan suggested.

Once a job is fouled up, anything done to improve it makes it worse.

Now I'm in suspense: do current kernels exhibit the same trouble? Did
you get a chance to bisect? Any other news?

Thanks again for a nice report.
Jonathan
