lenovo 3000 n100 thermal+hibernate

[Vasily Khoruzhick]

Hi, I have problems with thermal module on lenovo 3000 n100,

Sometimes after resuming from suspend, 
cat /proc/acpi/thermal_zone/TZ00/temperature says that CPU temp is 70 C and 
fan blows cold air. But coretemp says that CPU temp is about 40 C. 

Also I get following message on dmesg:
ACPI Exception (thermal-0471): AE_NOT_FOUND, Invalid active threshold [0] 
[20070126]

Reloading of module doesn't help, and I have no such bug in windows. 
I've tried kernels 2.6.20-2.6.24, and bug is present in all of them.

I can provide any additional info required ;)

Regards
Vasily
