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.

Clemens
