Subject: Slower CPU frequency reported by the kernel

Hi,

I'm using a PC with AMD 64 3000+ cpu which is theoricaly running at
2Ghz. But when looking at /proc/cpuinfo, the kernel reports that it
runs only at 1Ghz:

# cat /proc/cpuinfo

processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 15
model           : 12
model name      : AMD Athlon(tm) 64 Processor 3000+
stepping        : 0
cpu MHz         : 1000.000

fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes

wp              : yes

mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext lm
3dnowext 3dnow ts fid vid ttp
bogomips        : 2004.89

I tried with a 2.6.20-rc7 kernel and still have the same.

What's going wrong ?

thanks
