[Colin Ian King <1349740@xxxxxxxxxxxxxxxxxx>]

This error message occurs when the kernel runs the root PCI bridge _OSC
control method in your firmware and the execution fails, perhaps due to
a bug in the firmware or perhaps it does not exist.  The kernel hence
cannot determine the features supported or capabilities provided by the
device (as specified by your firmware) and hence has to disable PCIe
ASPM (Active State Power Management).

The downside of Active State Power Management not being enabled is that
the machine is less power efficient, however, one can force this on with
the kernel boot parameter "pcie_aspm=force" however, forcing this on may
cause system lockups.
