(Ответ для Vitaly Chikunov на комментарий #1) > Maybe related issue https://github.com/openwall/lkrg/issues/38 Authors comment: This isn't merely "maybe related", but it's a required fix for loading LKRG into kernel versions this recent. There's no point in trying to use non-updated LKRG on those very recent kernels. You really need to update LKRG to the latest first.
