I hit another manifestation of this problem today. Patch below. Only the patch description (error log) has changed. --- From: Randy Dunlap <randy.dunlap@xxxxxxxxxx> EEEPC_LAPTOP selects HOTPLUG_PCI. This causes failures (build error below) when CONFIG_HOTPLUG is not enabled, so additionally select HOTPLUG since kconfig 'select' doesn't follow its dependency chain. Also, only select HOTPLUG_PCI if PCI is already enabled. drivers/pci/hotplug/fakephp.c:55: error: implicit declaration of function 'pci_rescan_bus' ERROR: "pci_scan_slot" [drivers/pci/hotplug/pciehp.ko] undefined!
