No, it is regression. I can reproduce that without allowdac and any other unnecessary boot options. In later discussion Grant Grundler ask me apply patch that show 32 bit dma devices in my system. Results I attached to bugreport. Looks like only one 32 bit dma device in my system is ata controller, sata-nv. I can stable reproduce IOMMU out of space when I write data to sata drive.
