 What I did:
      - applied your patch to my tree
      - switched back to GENERIC (including WITNESS option)
      - enabled HIFN_DEBUG in my config
 
 But no change at all.  The dd command still hangs up after
 a couple of minutes and the only way out is to reboot.
 
 Also I don't see any debug output from the hifn driver. 
 
 Now I'm on
