Strange firewalld/systemd issue with nvidia drivers

[Fink Nottle]

OS: Ubuntu 16.04
nvidia drivers version: 375

There's a strange issue on my system that prevents firewalld from starting at boot if nvidia drivers are installed. firewalld has been enabled with "systemctl enable firewalld", and works fine with nouveau. Once nvidia drivers are installed, firewalld is somehow killed off early in the boot process. Starting firewalld manually still works after the system has booted. I couldn't find any errors in dmesg or /var/log/syslog. Enabling verbose or debugging modes in firewalld also doesn't spit out anything more. It looks like firewalld is just being killed off kind of intentionally. These are some messages from syslog:
