[Bug 392812] Re: Dell Studio 1555: cannot change display brightness after a while, other hotkeys and ACPI stuff begin to fail

[Pablo Olmos de Aguilera Corradini]

I upgraded the lucid kernel to 2.6.32-11 and it's the same. After the
resume acpi -t shows 0°C:

~$ acpi -t
Thermal 0: ok, 0.0 degrees C
Thermal 1: ok, 0.0 degrees C
Thermal 2: ok, 0.0 degrees C

~$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +0.0°C  (crit = +100.0°C)                  
temp2:        +0.0°C  (crit = +100.0°C)                  
temp3:        +0.0°C  (crit = +100.0°C)                  

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +77.0°C  (high = +105.0°C, crit = +105.0°C)  

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +74.0°C  (high = +105.0°C, crit = +105.0°C) 

And look what says the last dmesg lines after resuming:

[  298.296726] CPU1: Temperature above threshold, cpu clock throttled (total events = 1)
[  298.296731] Disabling lock debugging due to kernel taint
[  298.297216] CPU1: Temperature/speed normal
[  300.040033] Machine check events logged

Can you give me more details from your laptop?
