Most emergency transponders are made by a division of Honeywell, so there's chance that the A380 has the same or similar model. One report I read pointed to the use of particularly brittle Teflon coating on the loom wiring to the transponder and other equipment. Should the insulation crack and/or fall off, any equipment once shorted could give similar problems.
