For some reason each of the 5, 6 & 7 releases have issues with the

driver (there isn't enough swiotlb allocated by default for the driver to work properly, and the units for that parameter changed between 5 and 6). It's like this driver has bad luck or something.
To my best knowledge they shouldn't use swiotlb if you give the dom0 4GiB+ of RAM. I posted the exact same problem before and that was the recommendation I got. It works.

I'm not keen on letting dom0 take up so much memory :)
I'm giving swiotlb 256MB of memory (swiotlb=131072 on el6/7) and that resolved it for my configuration.
