Yes, that was the problem, now I am getting a new error, I do not care
for crash dump, but when I execute kexec -e it ask me to reserve some
space for it and use kdump kernel, which is not the case I am
interested:

# ./kexec -e -append="root/dev/sdb2"
Memory for crashkernel is not reserved
Please reserve memory by passing "crashkernel=X at Y" parameter to the
kernel
Then try loading kdump kernel
