kexec does not disable the outer cache before disabling the inner caches in cpu_proc_fin(). So L2 is enabled across the kexec jump. When the new kernel enables chaches again, it randomly crashes. Disabling L2 before calling cpu_proc_fin() cures the problem. Disabling L2 requires the following new functions: flush_all(), inv_all() and disable(). Add them to outer_cache_fns and call them from the kexec code.
