I am sorry to say, I tried to follow your instruction but finally the
out put is zero.

Okay I will try to update kexec-tools and do the experiment again then
report it.
In addition following I attached the dmesg info, among other things, I
saw one message: "Cannot locate EFI vmcore descriptor", this probably
implies that something is wrong, though I have no idea.
