So you are booting with gptboot off an SD card on the PC Engines system via legacy methods for a UFS root partition. GELI is not involved, correct? Sadly, there's no easy way to increase the verbosity of the early boot since the boot blocks have to live in such a constrained environment there's a strong bias against including debug code. But what we know is encouraging. We know that gptboot properly loaded, and that it found /boot/loader, loaded it, and then we had the issue. This helps us constrain things somewhat in testing. For the moment, we'll assume that gptboot is good, and concentrate on when /boot/loader went south. Before we do that, can I get any loader.conf and /boot.config /boot/config files you have? src/stand is easily buildable standalone these days, so my thought is trying to build it at r326550 and putting that onto into your image. src/stand stakes 1 minute to build on my box, so 5 on yours max :). You can even build it standalone in a separate tree if that would help keep whatever world you're using to do the builds purer. If we can't get satisfaction doing that, then we'll drop back to plan B: if you give me all the WITH/WITHOUT you are using, I could send you a tarball with about two dozen /boot/loaders to try which should make bisecting not a total pain in the arse. I'd likely toss in gptboot as well, since it's small. Let me know :) Since this is very early in /boot/loader's purview, I don't think kernel/world matter at all (apart from the fact that loader is built as part of world).
