Uh oh. Quite honestly, it's entirely possible that the hardware is FUBAR. I inherited this hardware, so I really don't know if something might be damaged. That being said, this would be the first thing that has found to be dead. > > Two PCIe hotplug slots seems to be detected by pciehp driver, although > I suspect there are really two because acpiphp driver seems to detect > only one slot.

How does the hotplug controller determine whether a device is present?
