Unexcepted shutdown in 2.6.28-rc5
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.

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

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.

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?

From the test it seems that the shutdown is caused by that the

CRT threshold 100
the temperature 144C
But the problem is why the temperature is above the critical threshold.
Quoted 1 line
From the acpidump the temperature is obtained by evaluating the
_TMP
object.
Method (_TMP, 0, Serialized)
{
If (DTSE)
{
If (LGreaterEqual (DTS1, DTS2))
{
Return (Add (0x0AAC, Multiply (DTS1, 0x0A)))
}
Return (Add (0x0AAC, Multiply (DTS2, 0x0A)))
}
If (ECON)
{
Return (Add (0x0AAC, Multiply
(\_SB.PCI0.LPC.WBEC.DTMP, 0x0A)))
}
Return (0x0BB8)
}Quoted 1 line
From the above definition of
_TMPobject the temperature will be related
with the following factor:
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.
