Can you please backport the following patch from upstream (random: try to actively add entropy rather than passively wait for it)? [https://github.com/torvalds/linux/commit/50ee7529ec4500c88f8664560770a7a1b65db72b] The culprit was systemd-random-seed.service which would take more than 20 seconds to initialize: root@asp-6c:~# systemd-analyze blame 23.551s sshdgenkeys.service 21.643s systemd-random-seed.service In systemctl journal, they have reported following messages: May 27 11:01:48 stratix10-abil rngd[140]: Failed to init entropy source hwrng May 27 11:01:49 stratix10-abil systemd-random-seed[159]: Kernel entropy pool is not initialized yet, waiting until it is. May 27 11:02:05 asp-6c rngd[140]: Initializing entropy source jitter This appears to be an issue with entropy pool not being populated quick enough and the fix from github helps with exactly that.
