Is that a problem? Yes. That mean iommu software or hardware is broken on your system. I have no other ideas how to track this down. I think now, this is a firwmare issue. BTW, you suspected that from very beginning :-) This could be also a driver issue, but AFAICT programing DMA do not differ on 6205 from other devices, so bug in firmware is much more probable reason of corruption.
