Hello,
It would be nice if we could reproduce this issue.

This article has been updated since then with a section[0] about a fix
authored by Linus[1][2] and merged in Linux 5.4. The gist of it that now
`getrandom()' will actively try to collect entropy in early boot, if it
is missing, by using the CPU jitter. The Debian wiki is saying the
same[3].
Since we are using actually using Linux-libre 5.4 as the default kernel
this issue should probably be closed.
