And based on the error it seems like an missing console due to ubuntu not starting at all, it mounts the system, but does not start.

I can't access to adb in real time actually.
Should I define a console ?

I think you need to define the console, i had to do that with the oneplus one. kernel panics are kinda hard to understand sometimes. i don't think adbd does not start at such low level, adbd get started by upstart. but you can force it to start with "break" in kernel cmdline (example break=top) to stop and start adbd where you can look around.

I know about those "breaks" but I don't know how to use them. I just need to chuck them in the cmdline ? in the ramdisk ?

btw, is the android container mountable?

In recovery

cd data && mkdir tmp
mount -o loop tmp system.img
cd tmp/var/lib/lxc/android && mkdir temp
mount -o loop tmp system.img

Mariogrip when I try to make the kernel from sources, it won't run it wants to compile /boot I need to make the kernel for mkbootimg

The kernel is inside boot.img, if it make a boot.img then it also made the kernel.

are you getting some errors? if yes paste them.

and also i texed you on the irc, but you quit. I use a webclient that does not give me notification so i might be little slow on the irc.

Here is the result : mountable (I did this one time previously btw)

EDIT : I made many tries and I finally set "break=mountroot" --> mountroot is the level of the crash for sure.

I felt tired, can I decompile boot.IMG?

Hey @mariogrip !
Long time has past and I investigated a lot.
My device [b]can't boot without a console[/b] (for many reasons that I can't even totally explain).
So I need to find a way to fix the crash and make Ubuntu Touch accept console flags.
If you know some Canonical Devs, could you ask them why the console is disabled ? And even what's make the kernel crash ?
