Hello,

I am newbie with the OpenBMC. We are porting O= penBMC for a platform which has 7 fan modules with two fans in each module.= I defined the pwm-tacho-controller@= 1e786000.conf, and when I run it, I see the following errors from the f= ansenor service. Here I pasted logs from the service, my conf file an= d other important information. I did not understand why the service is giving these errors. Appreciate your h= elp.
