Yes, that seems to be the most likely candidate.

Since then i installed the unstable kernel 4.14.12-2 and had no issues since on my desktop system (AMD A8-6500 CPU, F2A88X-D3H mobo). There was even a systemd update since and no freeze.

Although i had a freeze during an apt upgrade with the 4.14.12-2 on an update on my work laptop (i7-7820hk cpu, Dell Precision 3520). Did not have time to check the logs yet.
