Segmentation Fault with EasyDiffusion/ComfyUI on RX7600

Hi everyone, 

I’m facing an issue with EasyDiffusion/ComfyUI on my system using an AMD Radeon GPU. Every time I try to launch the script, I encounter the following error: 
120449 Segmentation fault      (core dumped)

Every time I attempt to use the GPU, I get the same error, regardless of which service I use. 
The strange thing is that for a few weeks on an older Linux Arch installation, the service was quite stable, but I have no clue what I changed now.

**System Details:** 
- Kernel: Linux 6.12.7-arch1-1 
- Display Server: Sway (Wayland) 
- GPU: AMD Radeon RX 7600 
- CPU: AMD Ryzen 9 7900 (24 threads) 

**What I’ve Tried So Far:** 
I’ve tested multiple ROCm versions (5.7, 6.0, 6.1, 6.2), but the issue persists. 

Any help or suggestions would be greatly appreciated. 

**Additional Information:**

vulkaninfo | grep "apiVersion" 
apiVersion        = 1.3.296 (4206888)

Re: Segmentation Fault with EasyDiffusion/ComfyUI on RX7600

That's normal for ROCM. It'll fix itself sometime in the foreseable future and break sometime in the foreseable future.
Check for and open a issue at comfyui/pytorch (the rocm one)/on some amd rocm repos
