Heyho!

With 2.6.31 (as packaged by Debian), kernel and BIOS are still fighting over 
who controls the fan on my Acer AOA-150.

If the system is idle, I see repeated 

Nov 20 08:07:12 laeggerli kernel: [100246.224141] acerhdf: temp 51      
Nov 20 08:07:12 laeggerli kernel: [100246.272136] acerhdf: fan OFF      
Nov 20 08:07:22 laeggerli kernel: [100256.328145] acerhdf: temp 51      
Nov 20 08:07:22 laeggerli kernel: [100256.376072] acerhdf: fan OFF      

(and the fan is turned on and off accordingly, using a rather noisy speed 
for ca. .5s every time.)

As soon as the system gets a bit warmer, fan is running on low speed and the 
system is much quieter.

ISTR reading that this should have been fixed in 2.6.31, or was that wrong?  
Did anything change in current kernels or the separate releases of the 
acerhdf driver?  I might be able to run newer driver releases, or at least I 
can provide more info if desired (and if you're patient to deal with quite 
slow round trip times from my side.  It's not an urgent problem either.)


cheers
