From which source ? With IDE disks, you should only get one interrupt per
disk transfer. in systat it's easy to check that the sum of the transfers
match the number of interrupts for the line.

From the output you posted it looks like you have a lot of TLB shootdown IPIs.
This is a MP issue, but I don't know the real cause (maybe too much RAM
touched at the same time ?)
