I was not that couraged to disable the shutdown completely, but I
compiled acpi with debug-statements to get more information. Here are
the results of the most recent shutdown:


Temperatures logged via cat /proc/acpi/thermal_zone/*/temperature >
file, triggered by the acpi-thermal-event:

Fri Oct 17 02:18:33 CEST 2003: event thermal_zone THRC 000000f0
00000001, THRC temperature:             39 C, THRS temperature:
      44 C

(please mind: far below the trip-points, which are around 80C)



A section from the acpid-log, where all occuring events are logged:

[Fri Oct 17 02:18:42 2003] exiting
[Fri Oct 17 02:33:52 2003] starting up



Attached the last few seconds of the system-log containing the
acpi-debug messages.


Is the code located in thermal.c around line 412 (function
acpi_thermal_critical, namely:
acpi_thermal_call_usermode(ACPI_THERMAL_PATH_POWEROFF)) the only
occurrence of code in acpi beeing able to do a shutdown?


I'm completely seeking in the dark. The only thing I understood by now
is that the actual temperatures _do not_ seem to exceed the trip-points.
(on my system 92C resp. 100C)


Regards,
Maier Gerfried

PS.:
I'm running kernel 2.4.22 with the acpi in this kernel. (no further
patch applied)
