Description

Hi,

My Asus M2N4-SLI motherboard equiped with an Athlon X2 has an it(4) hardware
monitor chip.

It seems that it stops the fan every 10-12 seconds and restart it every 7-8
seconds or so. I've tested in others Operating Systems I have installed on that
machine (linux) and the fan is not stopping at any time, so I think there must
be any issue under DFBSD.

History

#1 Updated by tuxillo over 3 years ago

I've left out all the it device lines in my kernel configuration file, thus
avoiding it(4) to be included and the fan did NOT stop at all.

#2 Updated by tuxillo almost 3 years ago

Can anyone with it(4) also check if the fan stops and start like in a loop?

#3 Updated by alexh almost 3 years ago

I can have a look at that if you remind me on some weekend, it's probably
related to bad PWM.

Regards,
Alex
