Multiple boot failures on new self build of system

[Pekkari]

Hi,

I successfully build the system using an ubuntu 18.04 debootstrap in my laptop,
after flashing the produced artifacts I find cm-14.1 looping forever in the initialization.
I have flashed it by using fastboot flashall -w, by flashing TWRP, and pushing the
zip file, and asking to clear dalvik/cache, or using adb sideload. All the ways of
flashing it yield the same result. Not happy with it, I downloaded the published
image and flashed it, having the same output. I collected some logcat where it
is possible to see multiple java exceptions and boot failures every 10s. The output
attached.

Any hint, or idea how to fix this out is appreciated.

Thanks!
