I may be misreading something but I see a
``working'' configuration where no memory address are assign
to the cards, and a ``non-working'' configuration where at least
prefetchable memory is assigned.

What I don't see in the ``working'' configuration is anything plugged
into the hotplug slots.  Nothing in bus numbers > 18.

The failure mode as I see it is actually attempting to hotplug a card
into those hotplug slots that don't have any resources that
won't work in either configuration but at least in the second configuration
you get an error telling you something that is wrong.

What card in the slot are you talking about that comes back up in one and
fails in the other?  All I see is simulated hotplug on non-hotplug slots.
