Description of problem: Upstream xen-3.1.1 contains a series of patches to better deal with swiotlb. This may or may not help some of the issues we've been seeing with certain block devices under Xen, but they should be evaluated and possibly included in 5.2. The xen-3.1-testing.hg changesets are: 15405, 15407, 15408, 15409, 15412, 15413
Some of these issues where reported by EMC, would you like them to test these patches to see if the issue is resolved?
