Cascardo, I did not tinker with other options but disabling ratelimit helped:
"StartLimitInterval=0"
"systemctl reset-failed kdump-tools.service" seems like a good option but
may not be needed if ratelimit is disabled..
Thanks

Talked to Thomas Richter for a fresh Ubuntu 18.04 where we can test the

the image where I found this issue for this test.
