During the boot process, my Ubuntu 14.04.2 takes about 11 seconds to complete the "random: nonblocking pool is initialized" step (this is the slowest step, FYI).
- What does this step mean?
- Is it normal to take a long time to complete it?
- Is there any solution to this?
A sample /var/log/dmesg log from my Ubuntu 14.04.2 is shown below:
