>Um, so 2.6.34 to 2.6.32 causes this spike in usage? 

Definitely yes. 

> What is the SWIOTLB (PCI-DMA32) usage between these two kernels 

I don't understand. What do you mean? The only difference is that I call 
up the swiotlb differently:

On pvops: iommu=soft
On rebased: swiotlb=32,force

BTW: changing to 64,force doesn't make a difference.

I attached a normal boot log of both kernels.

> and are the drivers (budget_...) the same version?

No, but a quick diff between the two source trees offer only minor 
changes that from the first look
do not seem to be related to DMA or whatever.
