It's freezing (actually it's an IRQ storm) when the cooler temperature
is increased and the speed of the fan should be increased.

I found when things went broken. It is the patch(es) as of
2006-01-13. The patch is at attachment. After applying (reversed)
patch acpi is working as well as management of the cooler speed.

Sam, should I do some other testing?

László, can you apply the patch (cd /usr/src; patch -R -p0
_the_patch_), make kernel and tell us if the problem go out?
As for me the reversed patch worked for current 6.1-PRERELEASE
(cvsupped some hours ago).
