Some systems and/or devices (such as riser cards) do not include a non-compliant implementation of PCI-e HotPlug that can result in devices not being attached (e.g. the HotPlug code might assume that a card is being unplugged and will power the slot off and detach it). This tunable can be set to 0 to disable support for PCI-e HotPlug ignoring the incorrect HotPlug state on these slots.
