Here's my "me too" data point.

I'm also seeing this on Xen 3.1.2, 64bit Xen, PAE Dom0 (2.6.18).  For 
me, it only happens if Dom0 is low on memory and into swap quite a bit. 
  Compiling a kernel with -j4 or so, with only 256M allocated to Dom0 
will trigger it.  I tried a number of swiotlb settings, none eliminate 
the problem.
