Try adding the kernel configuration boot option "printk.devkmsg=on" and reboot your computer.
When I tried that, dracut went to the next item in the menu for some reason. I also tried ignore_loglevel and early_printk=ttys0 with no effect. The message implies that it is systemd doing the ratelimiting, not the kernel. Something like ... systemd: printk: [25] messages were suppressed because of ratelimiting The number of messages seems to change, but is always in the 20s.
I'll see if I can find ratelimiting in the systemd documentation. There is nothing that sounds like that in system.conf; I've turned up everything for logging I could in there to no effect. That's /etc/systemd/system.conf
Since the original system boots and runs fine, I think it must be something simple. I'll keep looking.
