Is there an Adapt missing or something?

@ali-ramadhan we're getting an error here that I can't reproduce on tartarus. Can you reproduce on nautilis? Do you have an inkling what might be going on?

@glwagner Attempting to reproduce on Nautilus now.

I just ran (on this branch)

TEST_FILE="test_time_stepping.jl" CUDA_VISIBLE_DEVICES=3 julia +1.10.10 -O0 --project

on Nautilus (same V100 GPU but not in Docker) and locally (RTX 4090 GPU) and it passed on both.

So I'm wondering if it's a random/intermittent issue although the test group keeps failing... I can try to restart the Docker container.

If it's consistently failing then it seems like something is different between using the GPU inside a Docker container and outside 🤔
