And this time you are probably hitting this code in ext3_iget()
because you forgot to initialize inode->i_nlink.
if (inode->i_nlink == 0) {
if (inode->i_mode == 0 ||
!(EXT3_SB(inode->i_sb)->s_mount_state & EXT3_ORPHAN_FS)) {
/* this inode is deleted */
brelse (bh);
ret = -ESTALE;
goto bad_inode;
}
/* The only unlinked inodes we let through here have
* valid i_mode and are being read by the orphan
* recovery code: that's fine, we're about to complete
* the process of deleting those. */
}

This error corresponds to -ESTALE. See the file
include/asm-generic/errno.h in kernel source tree.
Hope that helps
