  Log:
  Minor tweaks to make it behave better:
  o When we're resetting the board, make sure that we error out the pending
    CCBs first.  Otherwise the aha_cmd won't accept further commands, such
    as those that are used to reset the card (AOP_INITIALIZE_MBOX).  This
    appears to cause a cascade failure where no more commands are possible
    to the card.
  o Reduce from 10s down to 1s the amount of time we're willing to tolerate
    the card being awol.  This helps the above case.
  o Add some error checking to two commands issued in the probe.
  
  I have a dim memory of gibbs@ trying to tell me about this problem a
  few years ago, so pointy hat to imp@ for sitting on it so long.
