[Bug 36014] Re: kernel can't scale cpu frequency

What I've written previously is incorrect. In fact, I set
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor to performance,
the CPU boomed up to 2GHz and, after ~ one second, the clock sank down
to 800MHz again...

Not only that, I had a look in /proc/cpuinfo and I still get the CPU MHz

processor       : 0

Please, help me on this, I'm using a 2Ghz CPU at less than a half of its

kernel can't scale cpu frequency
