           Summary: ACPI: Unable to turn cooling device 'on'
           Product: ACPI
           Version: 2.5
     KernelVersion: 2.6.24-rc3
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Power-Thermal
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


Most recent kernel where this bug did not occur: I really don't know, I think I
have this problem since end 2006 / start 2007.
Distribution: gentoo x86
Hardware Environment: Abit IC7-G
Software Environment: Portage 2.1.4_rc4 (default-linux/x86/2007.0/desktop,
gcc-4.2.2, glibc-2.7-r0, 2.6.24-rc3 i686)

Problem Description:
With FanEQ on, in the bios (if under 55°C then 60% fan speed) acpi is spamming
my messages file every six secconds see attachment dmesg_acpi. Without
logrotate my messages file would be 200mb+ today. This is really annoying. Now
I turned off this FanEQ thing in the bios and there are no bad acpi messages.
My fan is really loud now, is there a other way to contol it btw?
If you google for "unable to turn cooling device" you can see I'm not the only
one where this happens. Bugs #9227 and #9432 are related.

Steps to reproduce:
throttle cpu fan speed per bios, get the cpu hotter than ??°C and check dmesg.
