Please check your kernel config and/or bootloader.

What is wrong.
Many thanks for help

Your u-boot is too old. So it can not boot FDT kernel, unless the DTB is embedded inside uImage. Meaning when you created the rootfs Debian-4.4.0-kirkwood-tld-1 , you need to complete step 4:

4. Create uImage with embedded DTB for booting with older u-boots (2012 or earlier). Skip this step if you have installed the latest U-Boot for Kirkwood (or are installing this u-boot at the same time). 

Please replace kirkwood-goflexnet.dtb below with the correct DTB name for your box (see the folder /media/sdb1/boot/dts). 

Generate the uImage with DTB embedded inside: 
cd /media/sdb1/boot
cp -a zImage-4.4.0-kirkwood-tld-1  zImage.fdt
cat dts/kirkwood-goflexnet.dtb  >> zImage.fdt
mv uImage uImage.orig
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-4.4.0-kirkwood-tld-1 -d zImage.fdt  uImage
sync

Thanks for you help bodhi ,
I have done what you've suggested and it worked perfectly !
I am in debian now :)
During flashing the (old)u-Boot, I was not able to save all the files in /tmp for my reference later, which contain the dump of the original u-Boot that was installed (uboot-mtd0-dump): is there a way to recover them, before reflashing with a fresh u-boot ?

Thanks again.

See the Wiki sticky thread:

Section:
Backup and Restore NAND mtds - Pogoplug V4 original MTD partitions

Since you are running the GoFlex Net, make sure the flash_erase and the nanddump commands are adjusted for it if necessary. Post the series of commands that you are about to execute and I'll double check for you.
