Hi,

I implemented the initialization of hardware monitor ldn inside the ite chip. 
What do you mean "not working" stopped spinning?

Thanks
Rudolf

Yes, stopped spinning.

Thanks.

does a start spinning for a moment and then stops or does it not start
at all?

Could you please bisect it and verify that commit 80b627eb (Asus
F2A85-M: Move to ther proper SIO) [1] is the culprit?

Thanks,

Yes start spinning for a moment and then stops (Obviously until seabios 
menu.)

Okay. Already I have not had any problems with this version:

Thanks.

thank you for testing that version. To solve the problem the commit
breaking things is very helpful to know. Could you test the versions
afterward please? See the examples in the manual page of Git’s bisect
command (`git help bisect`) how to do a binary search. You know commit
80b627eb (Gerrit ID #4498) works and master is broken.

Thanks,

Paul

Double check: the chassis fan turns off. Sometimes, that's correct behavior
until things get warm, and the fan should turn on.

So you're sure the turning off is the wrong thing to do? In some cases it's
desirable for a chassis fan to spin up, then turn off, then turn on again
as needed, all under the control of a simple PID loop.

I just compile a linux kernel and the fan still does not work. For me, 
the chassis fan must always run continuously.

Hi

I think this is the problem: change the following line in the devicetree.cb

register hwm_fan2_ctl_pwm = "0x80"

To 0x00 For some reason automatic settings for fan2 does not work... or is badly 
set up.

Idwer: He uses the extra fan, not only the CPU fan.

Please let us know if this helps,

Thanks
Rudolf

So Rudolf, this just takes the control loop out of the picture and always
enables the fan? This stuff always confuses me.

Yes it perfect, my problem is resolved.

My fan is a "be quiet! pure wings 2" with 3-pin connector (therefore not 
PWM).
Thank you very much for your help.
