I have done some more investigation and have found out the following: - after doing a fresh restart, the "rate" reported in "vmstat -i" does not decrease. It keeps increasing slowly, when there is larger interrupt activity on atapci0 (irq22) - "systat -vmstat" reports zero interrupts, and "vmstat -i" reports this increasing rate - when utilizing the disks at 100% (copying large files) the interrupt rate is about 2300, which is truly high, but this correct number is shown only in "systat -vmstat"
