My 4.4.0-42 kernel which booted fine and was my workaround for months now hangs at boot like the later versions. I also discovered that I can boot in 42 recovery mode and I get asked the luks password at boot. I suspect a bad interaction with something else that got updated like possibly the nvidia graphics which I am rather dependent on due to CUDA etc.
