So I believe this is not an openssl issue, but something in the order that the kernel's RNG is initialized and openssh is started. Potentionally the RNG isn't initialized at all and you actually have to wait for the kernel to get it's random data from the slow way. So I'm reassigning this to systemd and openssh-server, I have no idea where the problem really is. Kurt
