Are you testing on a PowerMac G5 7,3? Should be in /proc/cpuinfo. I have a 7,3 model and cannot load the windfarm driver. It appears that the hardware on the 7,3 is not supported. I’ve been working to update the therm_pm72 driver to use the probe interface instead of the attach_adapter interface. Maybe you’re hitting this issue?
