From cbead9e2f82991302d1e60b3a0f2d4643a0597f4 Mon Sep 17 00:00:00 2001 From: Josh Boyer Date: Wed, 5 Apr 2017 17:40:30 +0100 Subject: [PATCH] hibernate: Disable when the kernel is locked down There is currently no way to verify the resume image when returning from hibernate. This might compromise the signed modules trust model, so until we can work with signed hibernate images we disable it when the kernel is locked down.
