When IOMMU is disabled, I/OAT DMA is successful on the second motherboard (X8DTH-6F). Specifically:
--- DMA Engine support [*] Intel I/OAT DMA support [*] Network: TCP receive copy offload [*] Async_tx: Offload support for the async_tx api
When IOMMU/X2APIC is enabled on the X8DTH-6F it fails to boot. Will keep doing more testing to see if I get anywhere w/regards to the IOMMU.
Proof of success:
