crashes with mysql and php7.0 on arm

[Schatzl]

I installed Linaro-Trusty-Server on Cubietruck-plus that works fine, but I wont for Upgrade to a newer Version.
The System don't will boot up.

The File /etc/lsb-release:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04
DISTRIB_CODENAME=xenial
DISTRIB_DESCRIPTION="Ubuntu 16.04 LTS"

The output from apt-cache:

linaro@cubietruck-plus:~$ apt-cache policy
