Those look relevant to me. Each RF daughterboard is supposed to have an EEPROM 
(memory chip) whose contents tell the gnuradio software what kind of board is 
installed. Your software is complaining that it couldn't identify the installed 
daughterboard(s), so their EEPROM(s) may need to be reprogrammed.

There's some discussion of the EEPROMs here that might be helpful:
