problem with [intr{swi4: clock (0)}]

Hi:

I would appreciate any help with this issue, this is a new machine built 
in the last week and if it is a hardware issue I want to return it.  The 
problem seems to have started in the last 24 hours or so.  I am seeing a 
really high cpu utilization for [intr{swi4: clock (0)}].  I have tried a 
couple things to troubleshoot:

rebuilt world and kernel
turned off Virtualbox ( did not load kernel module)
turned off in BIOS network, audio
installed disk from another similar machine, booted and it shows the exact 
same problem.

Here is what I see in top:

28.20% [intr{swi4: clock (0)}] - the process is using close to 30% cpu 
time.

I have no idea what could be causing this, any advice would be 
appreciated.  Thanks in advance.
