What will I miss if I keep debug.acpi.disable=3D"pci_link" fore= ver? I think it's dangerous and that you should just disable ACPI altogether if you wish to do that. Can you provide verbose dmesg's for the case with pci_link disabled and the case where it is not disabled? =2D-=20 John Baldwin <jhb@FreeBSD.org> =A0<>< =A0http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" =A0=3D =A0http://www.FreeBSD.org
