Unexcepted shutdown in 2.6.28-rc5

Unexcepted shutdown in 2.6.28-rc5

[Maxime Poncet]

Hi,

I have the same problem in 2.6.28-rc5 and 2.6.27.x :
my laptop shutdown automatically while working on it.

That problem doesn't appear in 2.6.28-rc3.

This terminal output show well the problem
$uname -a
2.6.28-rc5
$while true;
do cat /proc/acpi/thermal_zone/THRM/temperature;
sleep 1;
done

...
temperature:             51 C
temperature:             51 C
temperature:             144 C

And then it shutdowns because critical temperature was reached

Another thing that might be important : the output of dmesg
Every 5 seconds this message appears (not in 2.6.28-rc3):

ACPI: Transitioning device [FAN] to D3
ACPI: Unable to turn cooling device [ffff81007fb656d0] 'off'

Hope it will help you.

Maxime

Will you please add the boot option of "thermal.nocrt=1" and attach the
following output?
   a. acpidump
   b. dmesg
   c. cat /proc/acpi/thermal_zone/*/*

Of course you can file a bug report at
http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI
and attach the output of acpidump, dmesg.

Will you please add the boot option of "acpi.power_nocheck=1" and see
whether the following message still exists?
 >ACPI: Transitioning device [FAN] to D3
 >ACPI: Unable to turn cooling device [ffff81007fb656d0] 'off'

Thanks.

I will try 2.6.28-rc6 to check if this bug disappear.
I have tried several times to send attachement but I can't see my
email on http://marc.info/?l=linux-acpi&r=1&b=200811&w=2.
I think it's because I'am using thunderbird.

This message disappear using this boot option.

there are not many ACPI changes between 2.6.28-rc3 and -rc5.
it would be great if you can use git-bisect to find out
which commit introduces this regression.

thanks,

I wonder why _may_ be the reason of this.  Alex?

But the problem is why the temperature is above the critical threshold.

>From the above definition of _TMP object the temperature will be related

   a. DTSE . If the DTSE is non-zero, the temperature will be the
maixium of DTSE1/DTS2. But the DTSE/DTS1/DTS2 is defined in ACPI NVS
memory region. If the DTSE is non-zero, in theory the shutdown will
happen on the kernel of 2.6.28-rc3.
   b. DTMP. When the DTSE is zero, the temperature will be obtained from
DTMP, which is an EC internal register. 

Hi, Maxime
   As there exist some changes related with EC between 2.6.28-rc3/rc5,
Will you please use the git-bisect to identify which commit causes the
regression?
   Thanks.

Hi Zhao,
This issue is resolved for me in 2.6.28-rc7

But I am still getting the following message every 5 seconds
ACPI: Transitioning device [FAN] to D3
ACPI: Unable to turn cooling device [ffff88007fb63590] 'off'

I am using bitsect to find out which commit causes this regression.

Sorry for the late response.

It is good news that the shutdown issue is fixed in 2.6.28-rc7.
But the following issue still exists.
   >ACPI: Transitioning device [FAN] to D3
   >ACPI: Unable to turn cooling device [ffff88007fb63590] 'off'
Will you please add the boot option of "acpi.power_nocheck=1" and see
whether the above issue still exists?
   Thanks.

This boot option resolve this issue.
