I restart and boot with rhgb quiet removed I see
[ OK ] ...
.
but at the end there is a line that says
[ OK ] Reached target sysinit.target - System Initialization.


and it just stays there indefinitely.  I will restart under previous kernel and remove this one.  And retest when another comes by. 

Some storage devices have "quirks" that kernel usually works around. For example:

kernel: nvme nvme0: missing or invalid SUBNQN field.

I would take a close look at journalctl entries for a successful boot following the "sysiinit.target" line for informative messages.  

You can also check specific devices in the Linux Hardware Database -- some have comments that suggest kernel command-line

options to enable dodgy hardware.
