That’s now a _minimal_ example. Please see [Please read: make it easier to help you](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757)

Debugging an issue like this first requires getting rid of as much as code as possible while preserving the error. Doing so would reduce your last kernel to `SegmentsOnElement*segmentlength`, a multiplication if a device array and a scalar. That’s not supported on the GPU (requires allocating a new array).
