is this a regression? if yes, what's the latest kernel that this bug doesn't exist? please attach the acpidump of this box.

we can not say it's a 2.6.37-rc1 regression for now as the problem happens after running for nearly 5 hours in 2.6.37-rc1. Cristian, it would be great if we can find out how to trigger this bug in 2.6.37-rc1. e.g. please run "grep . /sys/class/thermal/*/*" after boot in 2.6.37-rc1, and attach the result and the dmesg output.
# grep . /sys/class/thermal/*/* /sys/class/thermal/cooling_device0/cur_state:0 /sys/class/thermal/cooling_device0/max_state:10 /sys/class/thermal/cooling_device0/type:Processor /sys/class/thermal/cooling_device1/cur_state:0 /sys/class/thermal/cooling_device1/max_state:10 /sys/class/thermal/cooling_device1/type:Processor /sys/class/thermal/cooling_device2/cur_state:0 /sys/class/thermal/cooling_device2/max_state:8 /sys/class/thermal/cooling_device2/type:LCD /sys/class/thermal/thermal_zone0/mode:enabled /sys/class/thermal/thermal_zone0/passive:0 /sys/class/thermal/thermal_zone0/temp:54000 /sys/class/thermal/thermal_zone0/trip_point_0_temp:127000 /sys/class/thermal/thermal_zone0/trip_point_0_type:critical /sys/class/thermal/thermal_zone0/type:acpitz /sys/class/thermal/thermal_zone1/cdev0_trip_point:1 /sys/class/thermal/thermal_zone1/cdev1_trip_point:1 /sys/class/thermal/thermal_zone1/mode:enabled /sys/class/thermal/thermal_zone1/temp:54000 /sys/class/thermal/thermal_zone1/trip_point_0_temp:105000 /sys/class/thermal/thermal_zone1/trip_point_0_type:critical /sys/class/thermal/thermal_zone1/trip_point_1_temp:99000 /sys/class/thermal/thermal_zone1/trip_point_1_type:passive /sys/class/thermal/thermal_zone1/type:acpitz

it's not reproduced. so let's say this is an intermittent EC failure. Cristian, how often did you see this bug? have you every tried to reproduce it successfully?
Can you reproduce the error message more frequently if you actively poll the temperature attributes? eg. while /bin/true; do cat /sys/class/thermal/thermal_zone0/temp cat /sys/class/thermal/thermal_zone1/temp done
Len Brown: Not message in dmesg

well, I don't know how to debug it if it can not be reproduced. how many times did you see the bug? could you please try the latest upstream kernel and re-open the bug once you see the problem again?
