Hi!

Linux ACPI system exhibits a vary curious behavior  on my 
Fujitsu-Siemens  pa1538 laptop. After an initial boot my laptop runs 
with slowly rotating fan. Fan continues rotating during the linux boot, 
gnome start and stops only when the temperature reaches active_trip 
point and fells below passive_trip. IMHO it is a little bit strange to 
hear rotating fan for a  core temperature less then 40 Celsius degrees.

google shows a lot of links, but I still cannot get what part of a 
system is responsible for fan start/stop -- hardware, kernel of some 
application?

And my second question is what is the preferable way to set trip points 
for current kernels?

I appreciate any help.

Kirill.
