Comment (by xyzzy):
OK, so it's happening only on CD boots (anyboot or ISO image).
What I've found is that it's seeing that bus_managers/pci/x86/v1 is unused
in module_init_post_boot_device, but the PCI module image is not unloaded.
Then when the FreeBSD driver tries to get the x86 PCI module, a new copy
of the PCI module image gets loaded, and pci_init doesn't get called on
that copy so gPCI in it will be NULL, hence the NULL access.
What's strange is why this isn't happening everywhere...
