Yes, see /proc/cpuinfo below.
With older kernels (currently still using Debian's 3.2.0-4-powerpc64
because of this problem), the fans go basically silent as soon as the
windfarm modules are loaded. With current kernels, the fans stay at the
level OF sets them to, until after a while they go into 'airplane mode'.
One thing I notice now is that the lines like
[ 9.539173] windfarm: CPUs control loops started.
[ 16.209962] windfarm: Backside control loop started.
[ 16.262274] windfarm: Slots control loop started.
[ 16.371642] windfarm: Drive bay control loop started.
no longer appear in dmesg with current kernels. Should they?
