Jim has worked with the A8N-SLI board. We
have worked with a newer version called A8N32-SLI Deluxe which has much better
PCIe support. Ours has only run the gen1 stack so I have no idea what it does
with the gen2 stack. As for the BIOS issue mentioned perhaps Steve W could take
a look and see if the comment from Jason makes any sense but my impression is
that everything was just fine.

I've not seen any problems with MSI/MSI-X with nforce4 and PCIe HCAs
on both my Asus A8N-SLI and HP DL145G2 systems.
Just building a kernel with CONFIG_PCI_MSI enabled might help, since
it changes the way the kernel numbers interrupts.
