Github repository for the kernel source is at https://github.com/150balbes/Amlogic_s905-kernel
and also includes the headers (source info is missing from this thread topic open post).

To build the whole image, see https://github.com/150balbes/Build-Armbian but its a bit involved. You can google forum.armbian  + github.com/150balbes/Amlogic_s905-kernel which is just the kernel. Can't tell you what branch of this kernel source tree to use and can't say if all the required patches are there (as they may be applied in the
Build-Armbian repo).

Have a look at https://forum.armbian.com/topic/12162-single-armbian-image-for-rk-aml-aw/page/10/?tab=comments#comment-96403
So that will be selinux=0 at the end of the APPEND= line in /boot/uEnv.txt
It's only a work around but it would be nice to get a fix.

I've done this (upgrading just kernel) previously and you need all the other /boot files from the 'new' (5.6-rc7 ) image. I've not worked out which files are key but you need u-boot*, emmc*, *autoscript_* etc.
AFAIK, kernel and initrd should be named /boot/zImage & /boot/uInitrd still.
Best to make sure the 'new' (5.6-rc7 ) fresh image boots from a fresh sdcard first and then work from that, which you've probably done.

Can't comment on your specific hardware but see point 3. of https://forum.armbian.com/topic/2419-armbian-for-amlogic-s905-and-s905x-ver-544/?do=findComment&comment=58673
I have TWRP custom recovery on one of my tv boxes so I can issue the reboot update command from a shell in recovery.

Hi,
I've uploaded it to megashares: https://mega.nz/#!N3AUWYQa!_IFkdHuTdh7Ynp9sLzaVyVj3BwDKJJRD7YFOlSEF6H0
Size on disk is 813558412 bytes and has an md5sum of 9d8a0b0868f51a6fcf33ca2bcbad6097.
 

I've uploaded Armbian_5.37_S9xxx_Ubuntu_xenial_3.14.29_server_20171226.img.xz to megashares
(md5sum a867b08685f25304847acfed7cc88803) - https://mega.nz/#!xqZgkQrB!g7HzYbusB0wifVxKbGwR-HPGETRvJMXyhu-u9SDy8pM
If you want any others, let me know - I've got kernel 3.14.79 as well.

What driver/chip do you want to build? Your better off getting the correct kernel source from https://github.com/150balbes/Amlogic_s905-kernel (or armbian build) if its a popular driver not enabled in the current /boot/config.
Search these forum threads for build instructions.
 

I think gnthibault I've mentioned this before in forums but is it possible confusion may be occurring between duplicate partition labels?
In fstab, you have LABEL=ROOTFS /  and in uEnv.ini etc bootargs=root=LABEL=ROOTFS
What I'm saying is the internal emmc flash and sdcard may have the same ROOTFS label.
Perhaps take the sdcard and relabel the ROOT partition with tune2fs or get UUID= value from blkid (and changing boot files in /boot/ and /etc/fstab ?
