It will obviously lockup, and nmi_watchdog doesn't work. Added the disconnect quirk patch, and lockups are gone and nmi_watchdog works. So there is no difference between the disconnect patch or the ACK delay patch. Though I found nmi_watchdog does depend on having either the disconnect patch or the delay patch (not an io_apic patch). You think the disconnect patch is better? In any event, they both indicate a behavior, and there maybe a better solution to all of it. Jesse
