Oops, I wrote a mistake: v4.10.0-42 is not more recent than v4.13.0-21 So I decided to take time to test your kernel.
For my first time I upgraded the kernel 'manually': v4.15-rc8 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15-rc8/
After booting (and the GRUB menu) I get a reboot before 2 seconds (after GRUB, on the next screen I only see the 2nd text line then the computer reboot).
