athlon x2 + 2.6.14 + SMP = fast clock

[Christopher Mulcahy <cmulcahy@avesi.com>]

I am running 2.6.14 SMP on an dual-core athlon x2 3800.
The system clock runs at roughly twice normal speed.

'cat /proc/interrupts' returns:
           CPU0       CPU1       
  0:   30834589   31107050    IO-APIC-edge  timer

On my other SMP systems ( admittedly 4-way 2.4.30 ) timer interrupts are
processed only by CPU0.

Perhaps unrelated, my kernel log is filled with these messages:
