you can always just look at the view config space window :-)
I don't see the VGA device or Network card in that view. I was thinking maybe that was why it doesn't get initialized?
Did you wait until after stage2? Things get set up in stage2 that are not initially visible.
Other than that, it's bug fix time.
Here's the contents of the Config space window Sorry it's sparse. I couldn't copy and paste out of that window.
BUS DEV FUN NAME 0 6 0 AMD-8111 PCI 0 7 0 LPC 0 7 1 IDE 0 7 2 SMBUS 7 3 ACPI 7 7 Simple Comms Controller (v2&v3, not in Factory BIOS) 10 0 AMD-8132 10 1 11 0 11 1 24 0 K8 24 1 24 2 24 3 1 0 0 AMD-8111 USB 0 1 1 4 0 Display Controller (Factory and v2, missing in v3) 1 5 0 82540 Gigabit Eth (Factory and v2, missing in v3)

is this as simple an issue as a missing dts entry? I'm not near the build machine right now.

I think our bus setup is not working. We never scan bus 1. That's a place to start llooking.
ron
one last note: I see this in the output.
PCI: pci_scan_bus for bus 01 pci_scan_bus: old_devices 0x00000000, dev for this bus 0x00011010 (dynamic PCI: 00:0b.0) PCI: scan devfn 0x0 to 0xff PCI: devfn 0x0
it's certainly trying to scan bus 1. So next guess is that the config space routing is wrong? or pci1234 is wrong?
Myles, if you get a chance, you might see in config space for 18:0.0 what is going wrong.
