For anyone interested, I opened
https://bugs.freebsd.org/bugzilla/show_bug.cgi?i= d=3D282493 for this.
 
Yea. This is a hang or a bad console. The warning is lame= and misleading.
 
Can you bisect?

Found it.

    uart: uart_getenv: check for= NULL class last, not first

    This allows one to specify d= t:XXXX when the default class isn't compiled
    into the ke= rnel. It's not an error to not have a class until we're done
  &n= bsp; parsing the spec, so defer checking until then.

-current as of today without this change boots just fine on the Ampere s= ystem in the Oracle cloud.

 
what's your loader.conf? this should only matter if something is set t= here...  

loader.conf:
