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.
