SYMPTOMS
If the SCSIPort driver encounters multiple busy or queue full request completions, it attempts to requeue requests in the logical unit's Device queue. When this occurs, the SCSIPort driver expects to find the Device queue in a busy state. However, it is possible for the queue to be in a not-busy state if it was drained by delivering LuNextRequests to the miniport driver. When this error occurs, the SCSI bus resets.
