The only reason I can think of, is during the boot process I parse the cards and write the data to some tmp files, which in turn are parsed when you load the Unraid Nvidia page.  So my guess is that during boot, it's a race condition and we're parsing the card before it's ready.   Can you try running this.   rm /tmp/nvidia/nvidia nvidia-smi --query-gpu=gpu_name,gpu_bus_id,gpu_uuid --format=csv,noheader | sed -e s/00000000://g | sed 's/\,\ /\n/g' > /tmp/nvidia/nvidia the
