The original poster had:
Architecture: amd64 (x86_64)
Kernel: Linux 4.18.0-2-amd64 (SMP w/2 CPU cores)

But I'm not sure if that's a real machine or some virtual host,
I'm going to guess it's a virtual host.

Anyway, on my laptop I get:
[ 12.675935] random: crng init done

If the TPM is enabled, I also have an /etc/hwrng, but rng-tools is
started later after the init is done.

On my desktop (with a chaos key attached)
[ 3.844484] random: crng init done
[ 5.312406] systemd[1]: systemd 239 running in system mode.
