changing dev.cpu.0.freq doesn't work

Hi,

I tried to lower the CPU frequency on my amd64 running 6, but all I get is:

root_at_kartoffel /root> sysctl dev.cpu.0.freq_levels
dev.cpu.0.freq_levels: 2201/-1 2063/-1 1925/-1 1788/-1 1650/-1 1513/-1 1375/-1 1238/-1 1100/-1 962/-1 825/-1 687/-1 550/-1 412/-1 275/-1 137/-1
root_at_kartoffel /root> sysctl dev.cpu.0.freq=962
dev.cpu.0.freq: 2201
sysctl: dev.cpu.0.freq: Device busy


In May I was using 6-CURRENT and it worked back then:

root_at_kartoffel X11> sysctl dev.cpu.0.freq_levels
dev.cpu.0.freq_levels: 2208/-1 2070/-1 1932/-1 1794/-1 1656/-1 1518/-1 1380/-1 1242/-1 1104/-1 966/-1 828/-1 690/-1 552/-1 414/-1 276/-1 138/-1
root_at_kartoffel X11> sysctl dev.cpu.0.freq=966
dev.cpu.0.freq: 2208 -> 966


I wonder what changed since then?
