    sys/dev/disk/aic7xxx aic79xx_pci.c 
  On Rev. B silicon, we disabled the enhanced busfree detection logic to
  close holes in detecting busfrees that occur after a packetized target
  transitions to a non-packetized phase.  The most common case where this
  occurs is when a target is externally reset so the controller believes
  a packetzied negotiation agreement is still in effect.  Unfortunately,
  disabling this feature seems to cause problems for the 7901B.  Re-enable
  ehanced busfree detection for this part.
