Fan management PowerMac7,2

Hello,

I was directed to this list on #ppc64/freenode IRC channel. I have PowerMac7,2 (AGP, 2xPowerPC 970(2.2) 2GHz) and I wanted to try kernel supporting kvm-pr module, which is not in 3.2.63 kernel provided with Debian Wheezy. I downloaded 3.14.24, compiled it using original config from 3.2.63 and after booting fan management does not work. I tried therm_pm72 (which is deprecated, but works well with Debian kernel) and windfarm_pm72 modules, but neither worked - after about five minutes from boot all fans go to maximum and stay this way no matter the CPU load or frequency.

I downloaded vanilla 3.2.64, compiled it the same way and there fans work with therm_p72 well. This kernel does not have kvm-pr, so I reverted to original kernel provided with Wheezy.

I looked to logs, i tried to search the web whether anyone had already the same problem, but it seems that nobody else described not to say solved this. Can anyone please point me to anything that would help? I can provide whatever log files required.

Thanks,

Martin Kukac
