Hi,

I have a problem with the interrupt level of my cpu. Over 50% is at 
normal operation used for interrupt. If i become root with the su 
command then the 50% strangely disappears for a couple of minutes and 
then it comes back again. Does any one recognize it? What can i do to 
reduce the interrupt to a minimum?

Tanks in advance,
Alex
