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.
