      We have a lab system that suddenly stopped being able to be deployed by the Assisted Installer; the BMH object is stuck in the "inspecting" state and has an event as follows:

      Unexpected exception UnicodeDecodeError during processing: 'utf-8' codec can't decode byte 0xf7 in position 13: invalid start byte
      

      Further investigation shows this is due to an error in processing an LLDP packet:
