[Bug 140468] Re: acpi unable to turn fan off

[ThomasNovin]

I have seen this two times on my 2.6.24-5.8 kernel. I'm running Hardy.

Feb  6 20:13:42 thomas kernel: [ 5494.292766] ACPI: Transitioning device [FAN] 
to D0
Feb  6 20:13:43 thomas kernel: [ 5494.292774] ACPI: Transitioning device [FAN] 
to D0
Feb  6 20:13:43 thomas kernel: [ 5494.292778] ACPI: Unable to turn cooling 
device [ee0f8318] 'on'

My fan runs at full speed (normally I can't even hear it).

I've got the same problem but on Hardy alpha 2 with 2.6.24-3 kernel. As
I noticed my CPU Fan doesn't work anymore on Haardy but works on other
systems.

from log:
Jan  9 00:04:26 blacktosh kernel: [ 1006.220108] ACPI: Unable to turn cooling 
device [dd14fb40] 'off'

What's the most important: My laptop (Toshiba Satellite A105) overheats
and hangs OS. Only hard power off helps in this state.

Hi,

I was having a very similar problem to this (see bug 70739). In
particular the negaive temp and fan settings problems seem to be due to
a broken acpi DSDT. Following this article:
http://ubuntuforums.org/showthread.php?t=623633, I fixed my DSDT and now
my temperatures are being reported correctly and the fan seems to be
functioning correctly.

Cheers,
Randall.

acpi off. desktop running at optimal performance. no further problems.
system upgrade to Gutsy. no further acpi issues. acpi preference: off.
