I've independently confirmed this on the 12.2BETA2 image; from my console:
...
FreeBSD 12.2-BETA2 r365865 GENERIC arm
...
Trying to mount root from ufs:/dev/ufs/rootfs [rw]...
Warning: no time-of-day clock registered, system time will not be set accurately
Growing root partition to fill device
random: read_random_uio unblock wait
load: 1.28  cmd: awk 39 [piperd] 0.12r 0.00u 0.00s 0% 2060k
load: 1.28  cmd: awk 39 [piperd] 0.14r 0.00u 0.00s 0% 2060k
...

time seems to be running about 500x slow.

I ^C'd each startup script that was stuck (I'm not as patient as
Mike), and got to a login prompt. I was able to login as root just
fine and the system seemed responsive for commands that don't sleep. I
tried `sleep 0.01` and that took about 5 seconds of actual time.
