It works for a few devices, but adding more than one PCI card starts up the wierdness. Disabling apic makes it happy again. For a while I thought it was just a linksys if_sk being flakey, but taking it out and putting a firewire card in had similar interrupt wierdness. I guess that means I can test any attempts to fix this :) -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
