Hi,
I am running an SMP-System (2 cores, Pentium D) and have a Pri-Card (Sagonma) running. This card "produces" many IRQs - but this is normal and ok. But I do not really understand, why I see this "irq-load" in top (%CPU) but top's header shows nearly 99% idle for all CPUs. I expected the same load in the header under "hi".

Thanks for an answer!
