I know this is way late. I managed to boot 4.9.206 finally on my test
system running Ubuntu 19.10.

It turns out, Ubuntu 19.10 defaults to LZ4 compression.

/etc/initramfs-tools/initramfs.conf
COMPRESS=lz4

Enabling the following worked for me.

CONFIG_RD_LZ4=y
CONFIG_SQUASHFS_LZ4=y
CONFIG_LZ4_DECOMPRESS=y
CONFIG_DECOMPRESS_LZ4=y

Stable release older than 4.19 will require the above change.

thanks,
