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:

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:

Not sure if this is relevant:

If you want dmesg, .config or other, contact me off list, I am not
