Krea2 crashes ComfyUI on ROCm 7.14.0a20260624

### 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

Krea2 should generate images.

### Actual Behavior

Step 1 in the KSampler crashes the process and leaves a trail of `amdgpu` errors in dmesg. This happens with or without `--disable-dynamic-vram` so it's not an aimdo bug.

I already have `PYTORCH_ALLOC_CONF=expandable_segments:False` because I get bizarre results with it on.

### Steps to Reproduce

Try to run Krea2 with ComfyUI + ROCm.

### Debug Logs

```powershell
The crash looks like this with `--disable-dynamic-vram`:

[INFO] Requested to load Krea2
[INFO] loaded completely; 25115.57 MB usable, 12532.86 MB loaded, full load: True
0%| | 0/8 [00:00

Start by reproducing Krea2 in the KSampler with custom nodes disabled, comparing runs with and without --disable-dynamic-vram and collecting the PyTorch/ROCm output plus dmesg. Done means the KSampler no longer crashes the process and Krea2 generates an image on the reported environment.
