Hi, i had this error.

UBIFS support 2 compression algorithms, zlib and lzo. They can be mixed
with one filesystem. You may specify which one will be used then
creating new files. It can be scepified as mount option. The default is
lzo. lzo is significantly faster but produce bigger files.

The qtmoko kernel have only zlib compiled in, is if you just run kernel
you'll see your message. To avoid it you should add mount option for
mounting rootfs. it's mount -o compr=zlib and kernel parameter
"rootflags=compr=zlib". this should be active in your bootloader.

Gennady.
