CAI, the hubs-v3-rebase branch is no longer up-to-date. You should just use Greg's usb-linus branch instead. (The patches went through a couple revs after the hubs-v3-rebase branch was abandoned.) I'll be cleaning out my xHCI branches shortly.

The first kernel also setup using IOMMU (intel_iommu=on). Removed intel_iommu=on from the kdump kernel parameter alone did not solve the problem.
