As others have said, it appears that's outdated.

Is there a real possibility that the hardware could fail the test 
without trashing the system?  It seems that if the DMA engine is faulty, 
it won't "politely" fail.  The whole system will crash or some memory 
will get corrupted and you won't know it.
