That makes a lot of sense. So we need both a "blocked, will be back soon" and "this PCI device is invisible" flags. A device going into blocked and not coming back would presumably transition into "invisible". I'm assuming we can't just delete the PCI device because the kernel needs to know that cell is there for future use/abuse.
