Original GitHub issue: https://github.com/ollama/ollama/issues/11055

What is the issue?

After upgrading to CUDA 12.8 (from a previously working CUDA setup), Ollama now runs models using the CPU only, whereas it previously utilized the GPU at 100%. No changes were made to the model or Ollama configuration besides the CUDA upgrade.
