As of now, no errors even when blasting traffic & forcing dhcp packets
as before. I haven't tried putting mtu back to 9k yet. OK means that
there are no obvious differences in behavior with or without DMAR all
else being equal.
There were some updates made to stable that could have fixed this - I'd
guess intel_iommu fixes helped.
If it helps, I'm still getting one error without DMAR enabled - at
startup, there's a DMA sync oops - mismatch of 72 bytes coming from
sky2. That oops was posted previously - with DMAR (re) enabled, there's
no related oops.
