rngd is called by '/etc/init.d/rng-tools.'
Restarting this in the terminal in the terminal, rngd runs for a few seconds (90-100% CPU), then is killed by rng-tools. On a reboot, rng-tools doesn't kill rngd. rngd continues indefinitely until I kill it manually.
# Short-Description: Support for hardware Random Number Generators (RNGs)
# Description: Loads RNG-modules specific to the hardware (if not automatically
# loaded by udev accoding to the PCI id) and starts the userspace
# daemon that passes the RNG data from /dev/hwrng to /dev/random
It may be a hardware issue, but I didn't run into this before 11.3. lsmod doesn't list a hardware rng module. It's an old computer, I wonder if there's just not a driver for this in 11.3?
