retitle 394971 [powerpc] [powerpc64] load the fan control modules. thanks Dear D-I team,
This bug not only affects the unofficial powerpc64 port, but also and more importantly the official powerpc port, on iMac G5 hardware. I reported the problem for the first time in the following installation report: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340980 I confirmed that it is not fixed in RC1: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=399334 It was figured out in the following report that the module windfarm_cpufreq_clamp had to be loaded before the windfarm_pm81 in order to start fan control: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=397942 I would like to stress out that once the fans start at full speed, it is not posible to stop them, as it is a low-level hardware preservation system triggered when the CPU reachs a defined temperature. Therefore, depending on the room temperature, the user will not have the opportunity to load the module by hand before the fans start. If it is not possible to integrate fan support to the installer, I would like to suggest the following addition to the installer errata: * Fan control is not supported during the installation on iMacs G5. You can safely run the installer with the fans at full speed. Please add windfarm_cpufreq_clamp and the relevant windfarm module to /etc/modules before rebooting, in order to have fan control on your newly installed Debian.
