It seems that iommu pci bus probe didn't enumerate device [01:00.2] and
[02:00.0], the corresponding context entries were not setup. Hence dma
fault generated when devices access the memory.
Do these two devices show in "lspci" output? How do these devices get
enumerated by the system?
Best regards,

They are there in the output, but it seems out of order:
