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

[Mirco Briosi]

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
bug!

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 13
model name      : Intel(R) Pentium(R) M processor 2.00GHz
stepping        : 8
cpu MHz         : 800.000
cache size      : 2048 KB
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 2
wp              : yes
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov$
bogomips        : 3996.01

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