That's very strange...  and it's also strange that it would be
constantly changing.  What version of e2fsprogs are you using?

Unfortunately, I need a raw image dump in order to be able to debug
this.  Can you create it using:

e2image -r /dev/sdXX -  | bzip2 > /tmp/sdXX.e2i.bz2

... and send it to me?

What's the underlying hardware for this filesystem, and I hate to ask
it, but are you sure it's not a hardware problem?

One thing you can do is to use e2image to create a sparse file on
another filesystem:

e2image -r /dev/sdXX /u2/sdXX.e2i

And then try to use e2fsck to check the raw e2image file.  If it is
successful, then but yet you keep getting failures with different
block groups and different inodes, it may be a hardware problem.
