@sriharshakandala can you get it down to a reproducible example?

[charleskawczynski]

.f is of type Type{Float32} which is not isbits.

I'm pretty sure we're just running into CliMA/ClimaCore.jl#1372

I would have though that this would have been fixed by JuliaGPU/CUDA.jl#2000, but maybe it's not in the version of CUDA.jl we're using.

We can use the $(FT(0))) trick for now
