I can find in the journalctl logs:

  cventin kernel: nvidia: module verification failed: signature and/or required key missing - tainting kernel

It seems that this has occurred since the legacy nvidia driver is used
(*nvidia-legacy-390xx-*).

The same issue has been confirmed in Ubuntu:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1805099

and according to the comments, this is a bug.

It's not though.  This is expected if you load an unsigned module on an
architecture where Debian signs all the in-tree modules.
