Kernel 2.3.31, two Pentiums 200mmx, but I noticed this:
/proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 5
model : 4
model name : Pentium MMX
stepping : 3
cpu MHz : 200.456554

hlt_bug : no
sep_bug : no
f00f_bug : yes
coma_bug : no

fpu_exception : yes

fpu : yes
fpu_exception : yes

Everything correct, but in dmesg I can see these:
..
Detected 200456554 Hz processor.
..
calibrating APIC timer ...
..... CPU clock speed is 180.4136 MHz.
..... host bus clock speed is 60.1374 MHz.

But it was (2.3.22):
calibrating APIC timer ...
..... CPU clock speed is 200.4525 MHz.
..... host bus clock speed is 66.8169 MHz.
cpu: 1, clocks: 668169, slice: 222723, nr: 2.

checking TSC synchronization across CPUs: passed.
Setting commenced=1, go go go
So... What has happened with my megahertzs?? Where are them?? Perhaps there is a
way to steal Mhzs in the new kernel code?? Linux power??
If someone will point me that I can have changed my setup, I can say that my
bios says 200mhz and /proc/cpuinfo also says 200mhz and I can't notice any
slowdown.
