      Description of problem:

      Baoquan He said:

      Yes, definitely, please add a shutdown(). That is a known issue already.
      The device not being shutdown explicitly could have on-flight DMA when
      you trigger kexec jumping into 2nd kernel. Before initializing the
      virtio-devces and irte tables, the on-flight DMA may continue sending
      irq to go through the old irte table if it's not overwriten, or get
      wrong error message if have been overwriten.
