Eval bug: llama.cpp CPU bound while inferencing against DeepSeek-R1 GGUF

Problem description & steps to reproduce

When attempting to use llama-cli to inference, it becomes CPU bound and is painfully slow (less than one token per second). nvtop shows that the GPU is 0% utilized (all CPU being used) despite 14 layers and 44GB offloaded to VRAM. I'm following the instructions outlined on Unsloth's blog and running the following command:
!build/bin/llama-cli \ --model DeepSeek-R1-GGUF/DeepSeek-R1-UD-IQ1_S/DeepSeek-R1-UD-IQ1_S-00001-of-00003.gguf \ --cache-type-k q4_0 \ --threads 64 \ --prio 2 \ --temp 0.6 \ --ctx-size 8192 \ --seed 3407 \ --n-gpu-layers 16 \ -no-cnv \ --prompt "<｜User｜>Create a Flappy Bird game in Python.<｜Assistant｜>"

Create a Flappy Bird game in Python.<think>
Okay, the user wants me to create a Flappy Bird game in Python. Let me think about how to approach this.
