I checked back with the CUDA-facing GROMACS developers. They've run the
code with 9.1 and believe there's no intrinsic problem within GROMACS.

as this is an internal non-descript cuFFT/driver error that is not supposed
especially in mdrun-test with its single input system, and it will prevent
him from using -pme gpu.

messages (which would have to be hardcoded anyway as cuFFT doesn't even
have human readable strings for error codes).
If you could share the output of
* gmx -version
* ldd -r mdrun-test
then perhaps we can find an issue (or at least report to nvidia usefully).
Ensuring you are using the CUDA driver that came with the CUDA runtime is
most likely to work smoothly.
