  It seems that there are some bugs. Pciehp and shpchp modules can not
  be loaded when the debug option is specified. Segmentation fault occurs
  with stack dump.

  pciehp_probe() or shpchp_probe()
    -> init_slots()
     -> get_power_status()
      -> slot_name() : This is called when the debug option is specified.
       -> hotplug_slot_name()
        -> pci_slot_name(slot->pci_slot)
                         ~~~~~~~~~~~~~~
                        Not initialized yet.
