[Regression testing on Xenial AMD64]
AMD64 kernel already has kexec support on Xenial. The attached patch applies
cleanly and builds on AMD64: https://pastebin.ubuntu.com/23950437/
== Installed kexec-tools built with ARM64 enablement patches ==
ubuntu@test:~$ dpkg -l | grep kexec-tools
ii kexec-tools 1:2.0.10-1ubuntu2.1 amd64
tools to support fast kexec reboots
ubuntu@test:~$
== Load kexec kernel and initiate kexec ==
ubuntu@test:~$ sudo kexec -l /boot/vmlinuz-4.4.0-62-generic
--initrd=/boot/initrd.img-4.4.0-62-generic --append="root=LABEL=cloudimg-rootfs
ro console=ttyS0"
ubuntu@test:~$ sudo kexec -e
== Successfully live booted kernel ==
