it means that some interrupt handlers will run w/ higher (than they
requested) ipl that is preventing otherwise lower ipl interrupts
from being processed. yeah when you get to say 10k ints/sec then
it might be an issue i suppose (:
things you can try is to look for your bios upgrade
or shuffle your pci cards in different slots.
also make sure all pci ints setting in bios are set to default.
