Just to clear up any confusion, v3.3 from sourceforge doesn't incorporate the
LZMA patches.  The squashfs3.3 tarballs from sourceforge and squashfs-lzma.org
are identical because the tarball on squashfs-lzma is taken unchanged from
sourceforge, there's additional patches on squashfs-lzma.org which add LZMA
support.  Obviously the CHANGES and README files don't mention LZMA because v3.3
doesn't use it, the credits file (ACKNOWLEDGEMENTS file) simply acknowledges the
work that squashfs-lzma.org has done in providing third-party LZMA support for
those that want it (I don't officially support LZMA compression in Squashfs
because it is not yet officially supported in the vanilla Linux kernel).

Failing to find root may be because you're still not generating a Squashfs v3.2
compatible filesystem.  The patch you mention elsewhere which adds '-no-sparse'
to mksquashfs, also adds '-b 131072' which will still generate an incompatible
filesystem, the block size must be 64K or less - the patch should be adding
'-no-sparse -b 64k'.

If you see the following error message after the initrd tries to mount root, you
still have an incompatible filesystem.

SQUASHFS error: Major/Minor mismatch, trying to mount newer 3.1 filesystem
SQUASHFS error: Please update your kernel

The filesystem should be version '3.0', you can use file or unsquashfs -stat on
the Squashfs filesystem to check the version.
