Ooooooooops, please forget, I just saw you published 4.0-2.21, that

Well -- it allows does the crash session to initialize, but it still needs work.
The "kmem -s[S]" functionality is broken, at a minimum because the
kmem_cache "objsize" and "lists" member names have been renamed
"obj_size" and "nodelists". There may be other issues, but I
haven't
gotten around to fixing this.
