Summary: Wrong trip points + unable to turn on cooling device
Product: ACPI
Version: 2.5
KernelVersion: 2.6.22-14-generic
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Thermal
AssignedTo: acpi_power-thermal at kernel-bugs.osdl.org
ReportedBy: lsmaneuf at orange.fr
Most recent kernel where this bug did not occur:
Distribution:Ubuntu gutsy ( same bugg on ubuntu feisty and pardus )
Hardware Environment: Desktop HP pavillon a629.fr / AMD Athlon(tm) XP2600+ /
Bios 3.08
Software Environment:
Problem Description:
Trip points are wrong :
cat /proc/acpi/thermal_zone/*/*
0 - Active; 1 - Passive
<polling disabled>
state: passive
temperature: 39 C
critical (S5): 100 C
passive: -248 C: tc1=4 tc2=3 tsp=60 devices=CPU0
active[0]: -266 C: devices= FAN
and an error is printed in the log files every 6 seconds :
ACPI: Unable to turn cooling device [debcbf18] 'on'
With previous kernell I "fix" the issue by overwriting the trip points :
echo -n "100:0:90:60:0" > /proc/acpi/thermal_zone/THRM/trip_points
but it is no more possible with this kernell.
I can run kernell with acpi=off, but then the power shut down is not working.
The message disappear if I kill thermal: sudo rmmod thermal.
I will provide results of acpidump and dmidecode ( running with acpi=off ) ...
when I'll found how to do it.
