If that would be the case I think the system would fail quite soon rather than on test 5. A guess is that this is a memory problem.Sure, once you call a subroutine and then try to return, corrupted memory would throw the processor into never-never land. And, that could leave the bus in a weird state, perhaps with no valid memory or device selected.
