If there is No fan rules, the fan is still possbile to be controlled implicitly
by other AML method. Otherwise, ACPI is fully exempted from this issue.
You need to customize DSDT to figure out which methods could be related to FAN. 

Maybe there are some potential ACPI interpreter bug causing this issue. Don't
know so far. Could you spot it for me?

Some think strang happened with new kernel. Alone fan not working and i wrote 
driver for i2c chip max1619 to set some ruls for it. It worked with older 2.6.x 
and now it working too, but with kerenl 2.6.11-rc1-mm1 fun start but wen it's 
cold can't stop.

Comment 6 Oleksij Rempel (fishor) 2005-01-22 02:12:39 UTC
Now i know my mistake. Some times i started linux after win. I think win 
konfyusd EC ruls and linux take it. If linux start therst then ewery think OK 
and fan working. If after windows - don't.
