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

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.
