I have the same problem with xen 3.1 and adding swiotlb=128 to my grub conf just caused xen to crash/panic. Not only that but this problem killed my dom0 root partition forcing all of the data into /lost+found which is oh so much fun. The only solution i've found to stopping this from happening is to force dom0 to use less than 2GB of ram. In my case i forced my dom0 to use 1024MB of ram leaving the rest (around 15GB) on vacation. Not a big deal since before 3.1 i always forced dom0 to use only 1024MB of ram anyway leaving the rest for the domU's.

I'm running 3ware 9560 controllers btw too if it matters.
