I'm not familiar with bumblebee, but I know that when you call the acpi methods for hybrid laptops to enable/disable the dGPU, it generates a pci hotplug event and the pciehp or acpihp driver will attempt to unload the driver. The acpihp driver was changed[1] to ignore the event, but as far as I know the pciehp driver still needs to be fixed.
