I built next-20171109 again with and without loadable module support enabled and it fails with it disabled but passes with it enabled (even without actually loading any modules): * with CONFIG_MODULES disabled (fails): https://lava.collabora.co.uk/scheduler/job/981215 * with plain multi_v7_defconfig and no modules loaded (passes): https://lava.collabora.co.uk/scheduler/job/981217 So I guess this means disabling loadable modules support has some interesting side-effects that cause the kernel to crash. I think the kci builds all leave modules enabled with multi_v7_defconfig, so the failing boots must be due to something else. Taking another look at the failing kci boots now... Guillaume
