X-WP-SPAM: NO 0000000 [YXCV] Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org I see that this list is extremely busy, I thought this is the place to go asking for help in debugging hibernation. If that's not the right place, please tell me where should I go. If that's the right place, please get me started. First - how can I retrieve some useful logs from failed resume attempts?
