Start with tests/detail/jit_lto/cutile_smoke.cu, especially the failing CutileSmoke.LaunchesCompatibleCubin test, and inspect the linked GitHub Actions job on a GB300 runner. Reproduce CUTILE_SMOKE_TEST in the affected release/26.10 or main nightly workflow; done means both smoke tests pass on GB300 runners.
