Thanks for the patch. In order to support partial upgrades and going back to an old kernel this needs to be made conditional, ideally using the same infrastructure I proposed in the patch I sent to #731345 last night (message id <1389216502.7769.40.ca...@hastur.hellion.org.uk>). After applying that patch changing your "DTB-Append: yes" to "DTB-Append-From: 3.12" should be sufficient. If you could try that in some of the scenarios I mention in that mail then I would be most grateful.

Just to confirm -- 3.12 is the first version which absolutely requires the appended DTB? The others work either because their DTB support was sufficient or because they ignored it in favour of the board file support? If that is the case then I think DTB-Append-From: 3.12 is the right choice. > I don't know if there are other models of guruplug, there only seems > to be a single guruplug dtb. This is something which will need to be solved for other platforms, I've got some vague ideas how to do it, but hopefully the guruplug won't be affected. Ian.
