Hi Luming, This module was build into the kernel. After make it a module and making sure it's not loaded, I still see the problem. Here is a more detailed problem: If I leave ACPI to manage the system, thermal zone TZ4 stays around 80 C. The moment I turn on fan C318, this zone *shoots* up to 100 C and stays there, no matter what. This fan I can't turn off again. Here is a cat of fans, thermal_zone status and temp. status: on status: off status: on status: on status: on status: on status: on state: active[2] state: ok state: ok state: ok state: ok temperature: 65 C temperature: 61 C temperature: 54 C temperature: 30 C temperature: 100 C This was taken during the compile of gcc. While not doing anything, the second zone drops to 54 C (currently at 61) Thanks for the time, Pieter -----Original Message----- From: Luming Yu [mailto:luming.yu@xxxxxxxxx] Sent: 2007/01/19 10:14 To: Pieter De Wit Cc: linux-acpi@xxxxxxxxxxxxxxx Subject: Re: Fan speeds on HP nc6400 and nc8430 Do you have psmouse module loaded ? (i.e. CONFIG_MOUSE_PS2=m) If yes, Please try remove it, and re-test it.
