Hmm, odd.
Can you check how it's aligned without your change? ie. in the original
binary, is it 4 byte aligned?
When you make the change, is the only thing that changes in the binary
the alignedness of dtstruct, or does it cause other things to move
around?
I don't think an unaligned dt blob should have any effect on the kernel,
ie. it should copy it in fine, but I'd have to look at the code.
cheers
