GROMACS version: 2024.1  
GROMACS modification: No  
**System Information:**

- Operating System: Ubuntu 22.04
- CUDA Version: CUDA 12.4
- GPU Driver Version: 550.54.15
- GPU : NVIDIA GeForce RTX 4090
- CPU : 13th Gen Intel(R) Core™ i9-13900K

This my cmake command

```auto
cmake .. -DGMX_BUILD_OWN_FFTW=ON -DREGRESSIONTEST_DOWNLOAD=ON -DGMX_GPU=CUDA -DGMX_DOUBLE=off

```

After I completed the compilation, I executed the `make test` command and encountered the following error.

```auto

Hi!

[This is an issue in our test suite](https://gitlab.com/gromacs/gromacs/-/issues/4888). It will be fixed in GROMACS 2024.2. For now, you can safely disregard this failing test; it does not indicate any actual problem.
