PROBLEM: (82157) (PATCH ID: OSF510-041)
********
  This patch fixes a panic or a system hang which could
  occur on a DS20E with drives attached to the motherboard
  SCSI interface (Adaptec 7895 based) or on an Ultra3 KZPEA
  SCSI adapter. In addition to system hangs or panics on
  configurations using Memory Channel adapters some
  configurations have exhibited SCSI device problems.
