i get the following error when trying to mount a squashfs partition on
an ARM system (edb9302) with linux 2.6.29-rc1:
mount /dev/mtdblock6 /mnt/
SQUASHFS error: Major/Minor mismatch, older Squashfs 3.1 filesystems
are unsupported
mount: mounting /dev/mtdblock6 on /mnt/ failed: Invalid argument
the image has been created using mksquashfs v3.4:
mksquashfs . /tmp/rootfs.squfs -le -noappend

You have to use a version of mksquashfs that creates file systems with the v4.0
layout, i.e. from the squashfs-tools on SourceForge.net:
git-cvsimport -v -d :pserver:anonymous@squashfs.cvs.sourceforge.net:/cvsroot/squashfs squashfs

You have to use the latest version of Mksquashfs in CVS available
from http://squashfs.org.
git-cvsimport -v -d :pserver:anonymous@squashfs.cvs.sourceforge.net:/cvsroot/squashfs squashfs

Does not look good! I have squashfs images which work OK in 3.3 and 3.4,
but now I try to boot 2.6.29-rc1 and it can not mount my squashfs root
partition!
Does it mean that squashfs4 is not backward-compatible? If so - I can
not use it - all my images are generated on 3.3 .. 3.4...

Backwards compatibility was dropped as part of the original review
complaints against mainlining. The new 4.0 layout was necessary to address
some issues again relating to the original review complaints. The 4.0
layout is designed to hopefully not require any further modification in the
future.
Ultimately this does mean the Squashfs mainline code will never be able to
read older filesystems. But, unsquashfs will always be able to read all
filesystem versions, and I'll maintain out-of-tree patches that add
backwards compatibility to the kernel code for those that need it. This
should be finished in the near future.
