Thanks for doing that and provding the results.

I suspect this, #1088159 and #1093371 have the same root cause.

Candidates for the breaking behaviour could be (just adding this now
for documentation purposes, so that we might not loose track):

6434af166441 ("xen: use correct end address of kernel for conflict checking") 
b1e6e80a1b42 ("xen/swiotlb: add alignment check for dma buffers")
1bd4e5a74da9 ("xen/swiotlb: fix allocated size")

(all of those did land in 6.1.113).
