I saw the Bruce's commit (cy_pci.c,v 1.10 1999/01/15 10:00:12 bde). Am I understand this right: if I configure my PCI card to an exclusive interrupt, and then turn on CY_PCI_FASTINTR, I'll get rid of ``silo overflows'' on it. Just out of curiosity. What is the ``interrupt latency in the FreeBSD kernel'' problem and what are the ``Bruce's "fast" interrupt hacks''?
