ACPI Exception

ACPI Exception

[Marcin Gozdalik]

[-- Attachment #1: Type: text/plain, Size: 1190 bytes --]

Hi

I am seeing the following in logs:

Apr 22 16:00:07 myth kernel: [   39.354031] ACPI Exception
(thermal-0479): AE_ERROR, ACPI thermal trip point state changed
Apr 22 16:00:07 myth kernel: [   39.354040] Please send acpidump to
linux-acpi@vger.kernel.org
Apr 22 16:00:07 myth kernel: [   39.354045]  [20080926]

I am using Ubuntu 9.04:

root@myth:/home/gozdal# uname -a
Linux myth 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:58:03 UTC
2009 x86_64 GNU/Linux

Motherboard is Abit AN-M2HD(MCP68) flashed with the latest BIOS.

The machine powers down sometimes because of an ACPI trip point:

Apr 22 17:27:19 myth kernel: [ 5272.004934] ACPI: Critical trip point
Apr 22 17:27:19 myth kernel: [ 5272.004952] Critical temperature
reached (121 C), shutting down.
Apr 22 17:27:19 myth kernel: [ 5272.004973] ACPI: Unable to turn
cooling device [ffff88006f841800] 'on'
Apr 22 17:27:26 myth kernel: [ 5278.204238] Critical temperature
reached (34 C), shutting down.

although I believe this is an error in measurement, as the temperature
probably wouldn't cool in 7 seconds from 121 to 34 Celsius.

Best regards

did this happen with earlier kernels, or did it start in 2.6.28?

please try 2.6.29.
please try it with CONFIG_HWMON=n

If it still fails, please file a bugzilla
http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI
and attach the acpidump there.

thanks,

Re: ACPI Exception

[Zhang Rui]

does the ACPI Exception happen during or after the boot time?
please attach the acpidump and full dmesg output.

please attach the output of "grep . /sys/class/thermal/*/*"

thanks,
rui

acpidump (compressed) is attached to the previous mail.

I attach the compressed dmesg output. ACPI exception happens during
boot but as you can see quite late in the process - around 40 seconds
after power up.

Currently the kernel is booted with thermal.nocrt=1 (otherwise it
reboots after a while)

Additionaly I noted a problem after resume from S3 - every 2 seconds
such a line lands in kern.log:

Apr 23 12:00:22 myth kernel: [22439.016355] ACPI: Unable to turn
cooling device [ffff88006f841800] 'off'

I attach the full dmesg-suspend.log with full suspend & resume cycle.

It happened with earlier kernels as well.

I will try.

> please try it with CONFIG_HWMON=n

Would that be only a workaround or a solution? As a workaround I use
thermal.nocrt=1 (or options thermal nocrt=1).
Should I try both 2.6.29 and CONFIG_HWMON=n?

I will as soon as I will have tried the options.

Re: ACPI Exception

[Marcin Gozdalik]

I am running the modified DSDT for the last 24 hours and the trip
point has not been triggered. Sometimes it happen after longer time
though.
The fixed DSDT does not help for "ACPI: Unable to turn cooling device
[ffff88006f851800] 'off'" messages after S3 suspend/resume cycle.

Best regards

Will you please add the boot option of "acpi.power_nocheck=1" and see
whether the issue still exists?

Yes, the Unable to turn cooling device after resume is still there

Your kernel version would be a good start :-).

The Embedded Controler driver has seen a series of fixes over time.
This error may be fixed for you in the upcoming 2.6.32 release.  So
you could try testing a release candidate.

It would also be good to tell us the vendor and model of the laptop.

Thanks

It sounds hard to pin this down, given how random it is.  Can we
assume you used a 2.6.31(-ish) kernel for some time, without seeing
these errors?  There weren't too many relevant EC changes since 2.6.31
(and at least the new DMI check should be easy to rule out).

You could create an entry on the bugzilla.kernel.org and attach the
output of "dmidecode".  That would at least record the existence of a
problem.  I'm afraid I can't think of anything else.  Possibly Alexey
will think of some other questions, now I've got the right address for
him :).
