Oof, you confused me. You are detecting bus PCI domain 0 bus 1 after PCI domain 0 bus 2. A dmesg would be more useful here. FreeBSD walks the PCI tree in a deterministic depth-first order, and we enumerate host bridges in the order ACPI enumerates them. Looking at the ACPI dump, you have 3 host bridges, PCI bus 0, and two uncore busses for your CPU sockets. So busses 1 and 2 must be children of bus 0. It would seem that bus 2 comes before bus 1 on PCI bus 0. You can tell this by seeing what the parent pcibX device of busses 1 and 2 are and looking at the address of that pcibX device on PCI bus 0. -- John Baldwin _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
