This looks little odd. Where is this address "99" coming from?

Few things.

- Have you reserved the space for second kernel?
- Have you compiled kernel as relocatable one or built a second kernel
  and trying to load vmlinux.
- What was the last working version or setup of kdump in your environment.

I would begin at running gdb at kexec to figure out where this seemingly
bad address "99" coming from.

CCing kexec mailing list, in case somebody has seen similar message.

Thanks
Vivek
