Bang ji le! It works with the patch you linked, xiexie!
I suggest it to be merged into mainline.

Anyway, is there a way to get sure that KASLR actually works now?
(I.e. how do I know if the kernel is really loaded to a random

Do you have any idea what might be different with my ThinkPad T400
that it is the only one of my machines affected?
