Rngd: Entropy Generation is slow, consider tuning/adding sources

A fresh installed F33 Workstation using Server-netinst.ISO with latest updates.

I got many of below in journal

#sudo journalctl --boot

Jan 20 13:48:57 amdf.lan rngd[233]: Entropy Generation is slow, consider tuning/adding sources

Findings:

  1. There is 1857017 – rngd generates lots of Entropy Generation is slow, consider tuning/adding sources, but no updates there yet.
  2. There is https://www.reddit.com/r/Fedora/comments/i2216e/not_enough_entropy_with_rngd/, I am not sure if I can force my old AMD cpu to work with rngd or I should try haveged
  3. adding kernel parameter rdrand=force do not help
