As of MAAS 2.5 the kernel and initrd are served from nginx when booting with pxelinux. Since you seem to be having issues with multiple files can you post the output of dmesg from each of your rack controllers? I would also ensure that the SHA256 of the initrd is found in https://images.maas.io/ephemeral-v3/daily/streams/v1/com.ubuntu.maas:daily:v3:download.sjson
