So pci_claim_resource can not find parent resource for device resource: we can not put non pref mem under pref mem. Can you send out result from ? lspci -vvxxx -s 0000:05:00.0 If it does have pref, could be of device layer does not pass the pref flag properly via pci_parse_of_addrs/of_get_property(node, "assigned-addresses". or the addr0 from "ranges" and "assigned-address" has different definition.
