Interesting news:  I tested 02a8fadd2c (August 19 snapshot at the link
above), and the bootonly.iso crashed the same way as you posted.
However, I tested the qcow2 VM image, from
https://artifact.ci.freebsd.org/snapshot/15.0-CURRENT/02a8fadd2c4dc4b78d6d93d9d8b70e9348a6de6d/powerpc/powerpc64le/
and the VM image booted successfully.  I don't know if that helps you
narrow down anything.
