Curious ACPI thermal_zone handling.

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.

Will you please attach the output of acpidump,dmesg?
Of course you can open a new bug in bugzilla and attach the output of dmesg, acpidump.
