Hi,

I just updated my -current sources, rebuilded my kernel, and noticed
some strange PCI messages at boot (full dmesg attached).

Where i previously had 5 PCI busses, the kernel now detect 9
busses. Some of them looks like ghost of real ones; by example, pci5
report devices from pci2 :

njoly@lanfeust [~]> pcictl pci2 list
002:09:0: Broadcom BCM5703X 10/100/1000 Ethernet (ethernet network,
revision 0x02)
njoly@lanfeust [~]> pcictl pci5 list
002:09:0: Broadcom BCM5703X 10/100/1000 Ethernet (ethernet network,
revision 0x02)

It seems that that the `pci_machdep.c' vs. `pci_intr_machdep.c' change
triggers this new behaviour; i tried to revert it and all PCI were
fine again.

Any idea of what's going on ?
Thanks.
