You mentioned that you had a pair of AMD R9 290X GPUs. Were you able
to passthrough AMD R9 290X GPU successfully?

I couldn't get them working properly on bare metal on my SR-2,
apparently due to the NF200 PCIe bridges, so I gave up on them.
That is what I was talking about in my previous email. They'll
probably work just fine if you have a motherboard that doesn't
use Nvidia NF200 PCIe bridges.

Previously I had a HD7970 "working". The reason why I say "working"
rather than working, is because domU reboot problems. It worked
fine on the first boot, though.

Unfortunately, I also had other issues, e.g. with multiple ATI
cards in the same machine when they aren't of the same generation
(e.g. HD4850 primary for dom0 and HD7970 secondary for passthrough)
I was seeing various strange crashes. Whether that's due to driver,
BIOS or VBIOS bugs or a combination thereof, I don't know.
