Comment 51 for bug 63550

This problem disappeared for me sometime while I was running Intrepid. Now that I've done the upgrade to jaunty, it's back.

I upgraded via the "do-release-upgrade" method.

The precise message is:

Apr 26 10:34:46 arwen kernel: [54142.600473] ACPI: Unable to turn cooling device [ffff88022f81abc0] 'on'

It occurs every 6 seconds, just like everyone else is seeing. In my boot messages, I see:

Apr 25 19:32:41 arwen kernel: [ 1.615740] thermal LNXTHERM:01: registered as thermal_zone0
Apr 25 19:32:41 arwen kernel: [ 1.615984] ACPI: Unable to turn cooling device [ffff88022f81abc0] 'on'
Apr 25 19:32:41 arwen kernel: [ 1.616017] ACPI: Thermal Zone [THRM] (51 C)

acpitool -t gives:

[arwen:jcostom](10:36 AM)
/home/jcostom$ acpitool -t
  Thermal zone 1 : passive, 55 C
  Trip points :
  -------------
  critical (S5): 60 C
  passive: 50 C: tc1=4 tc2=3 tsp=60 devices=CPU0
  active[0]: 50 C: devices= FAN

lm-sensors is also both present and started.
