By loading the CPU I mean running a program that is computationally intensive
(a python program that does large random matrix inversions).

I started to test a few kernels from the git repository. My fan problem appears
with a custom built 2.6.31 kernel, but not with Debian's 2.6.31
(linux-image-2.6.31-1-686). So I am n

@Klaus: I updated to the latest BIOS provided by TOSHIBA. That did not solve
the problem.
@Zhang: I will try to find the bug with git-bisect, but I have never done it
before, so it

Updating my report above:
I told the guy to update the BIOS very early on and I thought he had done so.
As he continued to write about the problem I found this bugreport here and

booting with boot option "acpi.power_nocheck" solves the problem. The fan turns
faster when the temperature increases and slows down when the temperature
drops, thus effectively main

I've only tried kernel 2.6.30, 2.6.31 and 2.6.32. They all have the problem.
Also as I posted above, I tested with Lenny, kernel 2.6.30-2 and 2.6.26-2. With
2.6.26-2, main fan start

you've tried?

What happened at that time is that I rebooted right after compiling the kernel,
which explains the temperature of 86C. In that case, what happens usually is
