  A quick test showed this worked for me:

    cat /dev/zero > /dev/mem

  (Obviously you need to be root to do this!)

  The panic looked like this:

  <0>Kernel panic - not syncing: Fatal exception in interrupt
  <1>BUG: unable to handle kernel paging request at virtual address ffffd030
  .. etc ..
