I have seen this with latest kernels, the problem has been identified by Google in tty driver, google bug (b/28979140). Basically the deqp test stops randomly here because of parsing issues of .qpa results based on which cts-tradefed decides to delete the configs that have already been run, these paring errors just mess up the cts-tradefed's deqp test state and cause this crash. Fix from Google is in tty driver that fixes the parsing errors.
