--- Comment #16 from John Baldwin <jhb at FreeBSD.org> ---
The _ADR is probably not relevant.  The pcib driver uses _ADR as part of a
fallback to determine the PCI bus number of the bus under a Host-PCI bridge if
_BBN doesn't work or isn't present.  However, if you only have a single
Host-PCI bridge it is going to be using PCI bus 0 which is what it will end up
using (and that works since you find PCI devices).  If it was truly broken you
wouldn't find any PCI devices at all under the bridge.

Carlos, can you try disabling EARLY_AP_STARTUP in your kernel config to see if
that makes a difference?
