It looks similar.
Hi Sander, could you please test your system with the following options?
1. iommu=amd-iommu-perdev-intremap in xen.gz GRUB entry
2. pci=nosmi in pvops GRUB entry
3. iommu=0 in xen.gz GRUB entry [optional, only if (1) doesn't work for you]
We were seeing an issue which was caused by messed-up interrupt remap table.
George Dunlap's perdev interrupt map solved our problem.
Thanks,
-Wei

Wei,
Are those similar to what you had been seeing?
