Perhaps the issue is related to pybombs. You mentioned that you completely reinstalled via pybombs. I seem to recall that the pybombs installation puts the fpga source into a folder called 'uhd-fpga' or something like that. But, a manual UHD install puts the fpga source into a folder called 'fpga-src'. Whatever folder you are using for the fpga source needs to be on commit 'ebf5eed'. Maybe pybombs is simply checking out 'master' for the fpga source code rather than following the appropriate fpga commit that is associated with the uhd 'master'.
