Bug#713943: Lack of i2c_powermac module may be the cause
Hi, A previosu message in this big suggested that the i2c_powermac module may be involved. I can confirm that this module is missing completely for the 3.12 kernel (there is no module of that name in the /lib/modules/3.12-1-powerpc64/ tree) whereas for the 3.4 kernel this module is available and is being auto-loaded.

Manually loading the i2c-powermac module results in fans that run at the normal. expected low speed. I will be adding this to /etc/modules as a workaround for this issue. A question about kernel modules, can one module (eg windfarm_core) be made to depend on and auto-load another (eg i2c-powermac)?

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?

Does it matter whether you load i2c-powermac before or after the windfarm modules? Loading after is fine. I therefore assume that loading before is also fine.

I have a single processor MacPro G5 PowerMac7,3 running Jessie. model : PowerMac7,3 machine : PowerMac7,3 motherboard : PowerMac7,3 MacRISC4 Power Macintosh detected as : 336 (PowerMac G5) I also have a dual core G5 PowerMac11,2 but it's running MacOS-X. The 7,3 has exactly the problem described. Adding the line i2c-powermac to /etc/modules is enough to fix the problem. As for the windfarm driver on that machine, $ lsmod | grep -i wind | wc -l 0 Sometime soon, I'll put a spare disk into the 11,2 and install Jessie on it. I'll give results and CC this bugreport.
