Description

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

I expect to see the progress go from 0% to 100% and get an image

### Actual Behavior

The progress bar stays at 0% for more than 10 minutes. Console shows nothing, my monitoring software shows my GPU usage at less than 9%. CPU also at idle. It's as if ComfyUI is not running my prompts at all.

### Steps to Reproduce

I honestly have no idea how to reproduce other than you wanna install ComfyUI for Linux AND intel GPU (Mine is an ARC A770)

Research direction

Start at the main.py entry point and inspect the execution path after the log line "got prompt" on Linux with an Intel Arc A770 and PyTorch XPU. Use the supplied runtime logs to determine where progress stops after model loading; done means the prompt advances from 0% and produces an image on this setup.
