From the
lspci hex output:
Note that some PCIe chip sets with a x16 link may not support a PCI
Express x8 link width. A link is required to support only its maximum width
and x1. Check the motherboard specification to determine if its PCIe x16 slot
can autonegotiate to x8.
On some motherboards, the PCIe slots are all the same physical size
required by a x16 slot, but electrically they are different widths. Check the
motherboard specification for the supported width of each of the PCIe slots.
