ACPI: Unable to turn cooling device off

[Markus Kilås]

My syslogs are filled wit the following error message:

ACPI: Transitioning device [FAN] to D3
ACPI: Unable to turn cooling device [ffff88013fa3aec0] 'off'

Even when the fan is turned off the messages continues.

The output from lsmod shows that both the fan module is not used, perhaps that is the problem?

Hi Markus,

Seems related to the following upstream bug: http://bugzilla.kernel.org/show_bug.cgi?id=9432 (and subsequently http://bugzilla.kernel.org/show_bug.cgi?id=11000) . Care to try booting with "acpi.power_nocheck=1" to see if it helps? Thanks.

Hi Leann,

Booting with acpi.power_nocheck=1 seems to work. The error messages are no longer in the log.

Thanks

I have a Toshiba Satellite A505-S6965 and am so happy to report that the acpi.power_nocheck=1 worked for me to stop this message.

For those who don't understand what it means to "boot with acpi.power_nocheck=1" it means to add it to the boot options on the initial bootup (grub) screen before Linux actually starts booting. After it boots up, then sleep and resume it and see if it works to turn off the message by doing a "dmesg | tail". If it does, adding it to the boot line that starts up your system in /boot/grub/menu.lst (usually after "quiet splash") should make it permanent for you.

Thanx to the one who posted this work-a-round!
