The kernel-devsrc rework doesn't take into account localversion files in the kernel source tree. This might result in modules with an incomplete version magic when building out-of-tree using the SDK. Before: root@qemux86:~# insmod hello.ko [ 42.000212] hello: version magic '5.0.3-yocto-standard SMP preempt mod_unload PENTIUMM ' should be '5.0.3-my-custom-release-yocto-standard SMP preempt mod_unload PENTIUMM ' [ 42.008200] hello: version magic '5.0.3-yocto-standard SMP preempt mod_unload PENTIUMM ' should be '5.0.3-my-custom-release-yocto-standard SMP preempt mod_unload PENTIUMM ' insmod: can't insert 'hello.ko': invalid module format After: root@qemux86:~# insmod hello.ko [ 39.094288] hello: loading out-of-tree module taints kernel.
