Hi Thomas, I think kexec is broken with CONFIG_RANDOMIZE_BASE=y. Chao had raised this issue some time back when this option was introduced. I don't remember the details though that why it is broken. CCing Kees Cook. Kees, is there a quick fix to the issue. Sooner or later people will start enabling CONFIG_RANDOMIZE_BASE=y and broken kexec will be a big issue.
