distributions that have certain systemd versions in some cases
combined with patches to libcrypt for FIPS/FEDRAMP compliance, have
led to boot-time stalls for some hardware. The reaction by some
distros and Linux sysadmins has been to install packages that try to
do complicated things with the CPU and hope that leads to randomness.
To mitigate this, if RDRAND is available, mix it into entropy provided
by userspace. It won't hurt. and it will probably help.
