It works! Excellent. I've committed the 2 bugs needed to fix your box. However, there is another bug that this exposed that I'd like you to test. Can you update to the latest HEAD, apply the updated pcib_debug.patch, and boot with 'hw.pci.pcib_clear=1' set from the loader? That should exercise the bug I'm worried about and see if my fixes for that (recursively growing windows) works correctly. -- John Baldwin
