I have to think about how I can provide some better support. In the above we see that there are two AD7417, where the driver already exists. And below we have an LM75, which should be similar, if not equal, to the DS1775 (This one is available in the tree, but not yet used on your machine.) The real missing part is the LM87. Here we might need to write a new driver. But these missing drivers have no direct effect on the fan speed. They only help you to determine the right speed to keep the machine cool. Sure, we need them when we have a user land app which controls the whole stuff. But for now you (we) play the user land app :) > iichb1 pnpinfo name=i2c compat=k2-i2c iicbus1 unknown pnpinfo > name=lm87cimt compat=lm87cimt at addr=0x5a unknown pnpinfo > name=lm87cimt compat=lm87cimt at addr=0x5c unknown pnpinfo > name=temp-monitor compat=lm75 at addr=0x90 unknown pnpinfo > name=power-supply-monitor compat=pic16c72a at addr=0x94 unknown > pnpinfo name=cereal at addr=0x1c0 > My thanks to you (and others) for the explanation. > > On my system, setting a *.rpm sysctl to a value does not always have > direct correlation with the value subsequently reported.

Hehe, these two fans are PWM controlled while the others re controlled by RPM (see the verbose log and in the source, type 0 is RPM, type 1 is PWM). It is possible that my formula to calculate the RPM is not working properly. I'll have a look at and see what I can improve. Thank you for the feedback. Andreas
