Okay. I'm sorry but I'm not very clear with this. I'm just putting down here my understanding. So basically we have two mutually EXCLUSIVE hotplug drivers I can use for PCI Express: 1) "pciehp.ko" : We use this PCIE HP driver when our BIOS supports Native Hot-plug for PCI Express (which means that hot-plug will be handled by OS single handedly). 2) "acpiphp.ko" : We use this "generic" ACPI HP driver when BIOS allows only ITSELF to handle hot-plug events. Is my understanding correct? I would appreciate if you could help me gain a grip on this. Thanks a lot for the useful info you gave. Provided me with a new direction to work on.
