PC freezes to death when zram is enabled

### 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 am writing this post in the hope that they will add some kind of safety net for such cases or in case someone else experiences something similar.

### Actual Behavior

My PC freezes to death when zram is enabled on Ubuntu. For a long time, I couldn't figure out what the problem was. I didn't even know where to turn with the problem: ComfyUI, Canonical, AMD, or even Linus Torvalds himself.

### Steps to Reproduce

1. Turn on zram on Ubuntu (in my case it was 8GB zram on Ubuntu 25.10, no swap);
2. Run ComfyUI;
3. Start generate video (in my case it was Wan 2.1-2.2 and LTX-2);
4. Got black screen and the PC freezes completely.

### Debug Logs

```powershell
ComfyUI did not indicate any problems in the logs.
```

### Other

What didn't help:
1. ComfyUI launch arguments: lowvram, reserve vram; use split cross attention;
2. Reinstalling different versions of Mesa, from stable to the latest.
3. Installing the latest version of Ubuntu.

What helped:
Completely disabling zram.
