If the TBS driver works, why don't you use it?
The WARNING from the kernel log indicates a hardware bug in the PCIe bridge. Do you have the same card, and do you also get this warning with kernel 3.16?
I/O virtualization requires handling packets from different devices differently. Problems with DMAR might indicate that some PCIe device does not correctly identify itself as the source of PCIe packets.
