Hmm, can you let the boot hang for a while?  It should continue after
a few minutes if you wait long enough, but wait a minute or two, then
give it entropy so the boot can continue.  Then can you use
"systemd-analyze blame" or "systemd-analyize critical-chain" and we
can see what process was trying to get randomness during the boot
startup and blocking waiting for the CRNG to be fully initialized.
