Re: Driver for PC87372

Jean, Guenter,

Thanks for the feedback. Some more information on my setup: I am running
CentOS 6.4 / lm_sensors 3.1.1 / sensors detect 1.1. It looks like
sensors-detect does probe the SMBus by default but in my case did not find
an LM85 compatible chip. However, I manually loaded the lm85 kernel module
and that got it working.  So I think I should be able to modify
/etc/sysconfig/lm_sensors to automatically load the lm85 module on bootup?
Also it does return temperatures, fan speeds, voltages, etc.
