Unrelenting testplan D25219

[Robert Crowston]

I have seen this behaviour when the xhci controller was unable to perform DMA. In my case I had the system memory configuration incorrectly encoded on the pci-e controller.

What is the physical address to which the xhci controller is performing DMA? It needs to be in the lower 3 GB of the physical address space.
