Good, at least we know what the problem is, now we only have to find the root
cause. ;-)

So, pci_ext_cfg_avail(root->bus->self) returns 0 on your machine, which is kind
of unexpected (to put it lightly), so very likely we have uncovered a bug
in the init code.

Unfortunately, I may not be able to take care of this issue for the next few
days, I'll let you know when I get back to it.

Thanks,
Rafael
