This has nothing to do with "lights out during hibernate". This is happening because you changed the kernel on your machine after you booted, then did a hibernate. The new kernel no longer matches the kernel loaded in memory. The kernels have to be identical. We do a few checks to ensure this is the case, and that's the check you're seeing. If you're seeing that message all the time, just do another ZZZ and un-ZZZ to clear any old hibernate signatures from swap. Obviously this needs to be done without changing the kernel after boot. -ml
