Is your system 32bit or 64bit? Before putting the card, there was no memory problem right?
And after putting in the card, memory resources all get used up right (by IOV)? It looked like it is similar to this problem: http://communities.intel.com/thread/23318 >From above and here: http://www.mjmwired.net/kernel/Documentation/PCI/pci-iov-howto.txt it seemed that this hardware feature requires BIOS support, and so if ur hardware does not have it, SR-IOV is not possible, thus giving rise to those errors u have seen.
