As pointed out in my previous mail,
http://www.coreboot.org/pipermail/coreboot/2009-June/050342.html
I flashed the bios. Unfortunately, the thermal problem did not go away:


/var/log/kern.log still contains this message:

And when running the test program, the computer shuts down after about 5
minutes. kern.log contains this message.

The reduction of the shutdown time from 50 min to 5 min makes the
situation even worse.
