Krea 2 Crashes if load on anything but nvfp4

[trolly056]

Custom Node Testing

• I have tried disabling custom nodes and the issue persists (see how to disable custom nodes if you need help)

Expected Behavior

It was loading just fine some days ago, i will say patientx/ComfyUI-INT8-Fast-ROCM has never worked for me, it always crashed, maybe the same crash as this one?Idk. But fp8 loaded just fine and when int8 was officially implemented it also worked for me, but then one day i woke up and it stopped working. I'm not sure if fp8 was still working, but it's not right now. Only nvfp4 works.
I've deleted my comfyui and reinstalled multiple times. No avail.

Actual Behavior

Crashes when it tries to load, int8convrot = crash, fp8_scaled = crash, nvfp4 = works.

[patientx]

comfy is changing their code , now int8 doesn't work at all with native or custom node on my pc as well ... So this is most certainly on comfy's side since I don't keep changing base code myself ...

[aksugat]

New triton not working whit gguf nodes ! or guffs at all only on triton 3.6! or --disable-triton-backend and i have 7800XT rdna3

[aksugat]

Culprit was dynamic vram for guffs etc, i also vibe coded into rocm int8 node int4 support, problem atm is double vram usage it unpacks int4 into int8 cause no proper support yet from comfy

[Jules-A]

I can reproduce this crash on 9070 XT but I just downloaded it, so I have no idea if it worked before. patientx and aksugat, those are completely different issues though. Pretty sure those were because of the upgrade to Triton 3.7.1 but this issue occurs even on eager.
