While I am not sure, it looks like this configuration is related.
config AUFS_BR_RAMFS
bool "Ramfs (initramfs/rootfs) as an aufs branch"
help
If you want to use ramfs as an aufs branch fs, then enable this
option. Generally tmpfs is recommended.
Aufs prohibited them to be a branch fs by default, because
initramfs becomes unusable after switch_root or something
generally. If you sets initramfs as an aufs branch and boot your
system by switch_root, you will meet a problem easily since the
files in initramfs may be inaccessible.
Unless you are going to use ramfs as an aufs branch fs without
switch_root or something, leave it N.
Did you enable it?
