I haven't been able to reproduce this yet (trying with kvm, not
successful with bare metal), but one thing I've noticed is that
it occurs when either a PCI hotplug driver or the ACPI PCI slot
detection driver is loaded.

It's obviously because we have both

drivers/pci/pci-sysfs.c: pci_create_slot_links()

and

drivers/pci/slot.c: create_sysfs_files()

But what I'm trying to figure out is why I'm not seeing this on
x86 bare metal (although it does supposedly reproduce in x86
kvm).

Does sparc64 load any PCI hotplug drivers?

Thanks,
