Not for me, I fail to boot with

(this is iscsi root so I need the NIC).


I bisected it to "x86: remove the IOMMU table infrastructure" but haven't actually looked at the code yet.

Thanks. Looks like the sizing is going wrong.  Just to confirm, this is
dom0 on x86 and no special command line options?

Right.
