You can ignore them. They are for your keyboard and com ports and such and= =20 those were already probed via hints. Your PCI device at 7.2 is very weird = as=20 it seems to return 0000's for everything which is odd. You might consider= =20 disabling PCI power stuff (I think it's hw.pci.do_powerstate=3D0 or some su= ch,=20 check sysctl for a sysctl with 'power' and 'pci' in the name and set it to = 0=20 in the loader and see if that makes a difference on 5.x and 6.0). =2D-=20 John Baldwin <jhb@FreeBSD.org> =C2=A0<>< =C2=A0http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" =C2=A0=3D =C2=A0http://www.FreeBSD.org
