No such problems here:
CPU: AMD Athlon(tm) II X2 250 Processor (3013.74-MHz K8-class CPU)
...
hwpstate0: <Cool`n'Quiet 2.0> on cpu0
dev.cpu.0.freq: 1800
dev.cpu.0.freq_levels: 3000/30375 2300/25500 1800/21735 800/7900
dev.cpu.0.temperature: 37.0C
It seems that hwpstate, which adds support for 10h and 11h AMD families, was never
MFC-ed by mr@.
Perhaps I'd be able to do MFC to stable/7.
