Re: Linux 2.6.23-rc3

Hello Michal, 

This morning I have booted laptop, for a while fan had been turned off.
But then after a light load (compiling stuff & co), fan was turned on
and now it is still on. 

zilvinas@zv:~$ acpi -bt
     Battery 1: charged, 97%
     Thermal 1: ok, 48.0 degrees C
     Thermal 2: ok, 37.0 degrees C
     Thermal 3: ok, 46.0 degrees C
     Thermal 4: ok, 37.0 degrees C
     Thermal 5: ok, 32.0 degrees C
     Thermal 6: ok, 20.0 degrees C

Temperatures don't seem to be that high to keep the fan on.

Z.
