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. gozdal@myth:~$ grep . /sys/class/thermal/*/* /sys/class/thermal/cooling_device0/cur_state:1 /sys/class/thermal/cooling_device0/max_state:1 /sys/class/thermal/cooling_device0/type:Fan /sys/class/thermal/cooling_device1/cur_state:0 /sys/class/thermal/cooling_device1/max_state:3 /sys/class/thermal/cooling_device1/type:Processor /sys/class/thermal/cooling_device2/cur_state:0 /sys/class/thermal/cooling_device2/max_state:3 /sys/class/thermal/cooling_device2/type:Processor /sys/class/thermal/thermal_zone0/cdev0_trip_point:1 /sys/class/thermal/thermal_zone0/mode:kernel /sys/class/thermal/thermal_zone0/temp:27000 /sys/class/thermal/thermal_zone0/trip_point_0_temp:90000 /sys/class/thermal/thermal_zone0/trip_point_0_type:critical /sys/class/thermal/thermal_zone0/trip_point_1_temp:80000 /sys/class/thermal/thermal_zone0/trip_point_1_type:passive /sys/class/thermal/thermal_zone0/type:acpitz 2009/4/23 Zhang Rui <rui.zhang@xxxxxxxxx>: > 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 > > On Wed, 2009-04-22 at 23:58 +0800, Marcin Gozdalik wrote: >> 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@xxxxxxxxxxxxxxx >> 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 >> >> -- >> Marcin Gozdalik <gozdal@xxxxxxxxx> > > -- Marcin Gozdalik <gozdal@xxxxxxxxx>
