[SOLVED] ODroid-C2 kernel versions differ, modprobe fails

[steinpfeffer]

Hi all,

today I failed to start the Docker daemon because of missing iptables module. The module cannot be loaded because it cannot be found in the expected directory.

After having checked what could be the cause I recognised that uname -r tells me that I am running on kernel 3.14.79-28-ARCH while pacman tells me that version 3.16.85-1 is installed (this is where the modules live).

In order to streamline the kernel versions I tried to run $this->bbcode_second_pass_code('', 'mkinitcpio -P'). This approach failed because:

$this->bbcode_second_pass_code('', 'depmod: WARNING: could not open modules.builtin.modinfo at /tmp/mkinitcpio.qHXHCF/root/lib/modules/3.16.85-1-ARCH: No such file or directory')

open modules.builtin.modinfo is really missing in /lib/modules.

What else can I do?

Have you run `pacman -Syu` recently without rebooting afterwards? If so, first reboot and then try starting Docker.

In fact I did multiple reboots after the last pacman -Syu.

The main problem IMHO is the divergence between the installed and the run kernel version.

Ok, I found the culprit. In my setup I boot from SD card but the actual system runs from HD. This means that /boot is where new kernels will be installed but the source for booting is (in my case) /dev/sdcard/boot.

Not the best setup in the world.
