Looking at that code, it's all trivial, and it definitely unplugs properly.

Lack of entropy still sounds _very_ strange, and you . Are you doing
something odd at boot?

Does the boot continue if you press keys on the keyboard, or how did
you decide it was about entropy?

I guess sysrq-'t' followed by enough keyboard input to unblock the
boot process should give you something in dmesg that shows what is
blocked?
