The pci_disable_device function is defined in the source file of the kernel pci module. 

Let the pci_disable_device function be a working parameter of the kernel pci module.

GRUB boot commands works when I type pci=disable_acs_redir=pci:12D8:2308 in linux pci module.

When I type pci=pci_disable_device=pci:12D8:2308 to disable the hardware, it gives unknown parameter error.

what is the reason of this ?
