Unstable unpacker output in DaVinci tests

Many times during the ci-tests, some DaVinci tests fail due to the unstable output of the unpacker in DaVinci jobs. See Moore!3422 (comment 8307070).

The unpacked result seems to be stable, but the unpacking buffer sometimes gets split for unknown reasons.

TODO:

  • Write the unit test to reproduce the problem: only unpacking data and check the unpacked result
  • Check buffer size to understand the splitting behaviour
