AFAIR the problems started > with the change to dtb/dts. Which kernel version? Can you give me a kernel version when it was good and a version when it was bad? For a few kernel versions it was possible to boot both DT and the old setup file. It would be great to confirm it was the swap to DT, and not some other kernel change at about the same time. My gut feeling is that the change to DT is not the issue. But this is all speculation at the moment, we need some hard evidence. Andrew
