The underlying reason for the mismatches is that, because the uhd/fpga-src submodule points to a commit on fpga, we need THAT commit to be on the fpga master branch. So, by necessity, we'll always have some amount of time in which the two repositories are out of sync (that is, fpga is ahead of uhd). This window was longer than usual, and we apologize for that. In the future, if hiccups like this are an absolute deal-breaker for you, please consider using the submodule pointer, or one of the UHD release branches.
Regarding PyBOMBS, as far as I can tell, there isn't a silver bullet in this situation. I like the idea of the uhd-fpga recipe tracking uhd/fpga-src, but I don't think git can clone submodules. The best thing that comes to mind is to have the uhd-fpga recipe populate the uhd/fpga-src submodule, which just saves the effort of manually updating the submodule. If you have a better suggestion, we'd love to hear it.
