    I've been having some trouble with nforce motherboard and
    FreeBSD-5.2.1-CURRENT. The only combinations that I have found
    to work consistently are disabling ACPI with hw.acpi.0.disabled="1" and
    either no PM or using apm, or enabling ACPI and APIC disabled with
    hw.apic.0.disabled="1". This solution would not work for SMP kernel.
        I'm not sure of the exact problem but there seems to be an irq
    sharing issue when both ACPI and APIC are enabled. These coexisted with
    11/2003 5.1 but as of 5.2.1 there have been problems for me. Onbord
    Lan, USB, and either ACPI or APIC cannot coexist. Boot with ACPI&APIC,
    start if_nv (nvnet) using dhclient, USB-OHCI mouse.
    Use the onboard lan, i.e. open web-browser. USB no longer responds, and
    onboard lan timeout. No way to restart either without reboot. Both work
    perfectly if either ACPI, or APIC is not started. The mouse and lan are
    both
    on pci0 at irq 10.
