The kernel probes them in whatever order it walks the PCI bus. What udev does afterwards is a distro question. Does the order of the two probe reports every change or just the final udev result - ie are they always found mac xx:xx:03 then xx:xx:05 ? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
