Thanks for all the testing. It seems the bug may be in the kexec-tools package and not the kernel. Can you test the kexec-tools package that comes with 14.04.1 on your vivid installation? It can be downloaded from:
https://launchpad.net/ubuntu/+archive/primary/+files/kexec-tools_2.0.6-0ubuntu2.1_amd64.deb
You will probably need to remove the current version with 'sudo dpkg --purge kexec-tools'
