Right, so this fixes the issue on my box, courtesy of Joerg. WE basically don't disable the IRQ on MSI-enabled devices. The AMD IOMMU uses a barebones PCI device but not a PCI driver, which would be an overkill.
Well, not only overkill, but actually harmful. As I just wrote to Jiang, a device can be forcibly unbound from its driver, which is something we don't want for the IOMMU.
