I just loaded the latest Debian-ports powerpc64 installer on a PowerMac dual-core G5 that I had lying around. It installed kernel 4.16.0-1-powerpc64 from the CD. After the install finished, I did an update/upgrade and that installed kernel 4.17.0-3-powerpc64. A few minutes after rebooting with the new kernel the “wind tunnel” fans started up. I then rebooted with the old (4.16) kernel. The fans did not start up. Back in the old days of Linux kernel 3.x, the fix for wind tunnel fans was to load the “i2c_powermac" kernel module. Nowadays, that module is built-in so it isn’t necessary (or even possible) to manually load it. I checked the config files, and it is still built-in on both the 4.16 and the 4.17 kernels. Anybody know what changed and what can be done about it? Thanks! for any help you can give, Rick
Have a look around for something called "windfarm". It may even be located somewhere down under /proc and should be a kernel module. I have had the same behavior with a G5. Wind farm sorted it all out. Dennis
