I'd also like to add that my high-spec x86 laptop exhibits the same issue as
my Edgar Chromebook.

Here's my dmesg:

The most interesting line:
[ 90.811633] random: crng init done

I waited 90 seconds after boot to provide entropy myself, at which point crng
init completed. In other words, crng init only completed because I provided
the entropy by smashing the keyboard. I could've waited longer and crng init
wouldn't have completed without my input.

Mind you, this laptop has a 45W CPU, so power savings were definitely not
considered in its design. Do you have any machines that can provide enough
boot entropy to satisfy crng init without requiring user-provided entropy?
