As further information, I have a machine with the same NIC and chipset
(Intel S1200BTL motherboard) but with quite different lspci -vvv

Most notably it appears as though MSI-X is not enabled on the
Supermicro, and ASPM L1 is. There appears to be no difference on the
Supermicro as to the MSI-X status when booting with IntMode=1,1 compared
to without it.
Thanks,
Chris
