The only real challenging test is to run Linux :-) No other test I've
seen so far loads the system in a comparable way, especially when you
have the root filesystem mounted  over  NFS,  so  a  lot  of  network
traffic (= DMA) is going on all the time.

All other tests more or  less  boil  down  to  simple  read  /  write
accesses;  this  is  fine  to  detect real hardware problems, but not
sufficient to verify that burst mode accesses work reliably.

Best regards,
