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:

==> Further issues with the X9SRL-F -- does this board support ASPM or is
this a Linux/ASPM implementation issue?
[ 0.632170] pci0000:ff: ACPI _OSC support notification failed, disabling
PCIe ASPM
[ 0.632239] pci0000:ff: Unable to request _OSC control (_OSC support
mask: 0x08)
