Re: Linux messages full of `random: get_random_u32 called from`

I noticed "systems without sufficient boot randomness" and would like to add to this.

With the changes to /dev/random going from 4.16.3 to 4.16.4, my low-spec Chromebook does not reach
the login screen upon boot (it stays stuck on a black screen) until I provide a source of entropy to
the system via interrupts (e.g., holding down a key on the keyboard for 5 sec or moving my finger
across the touchpad a lot). After providing a source of entropy for long enough,
"random: crng init done" prints out in dmesg and the login screen finally pops up.

Detailed information on my system can be found on this bug report I recently worked on:
