3bit working, 4bit not

Using latest llama.cpp as of today. Output was garbled on UD-IQ4_XS and the NL quant. Worked great at 3bit, maybe user error 🤷

this looks strange. unsloth UD-IQ3_XXS works for me while UD-IQ3_S failed when I connected it into claude code variant.

For me both UD-IQ3_XXS and UD-IQ3_S fails, with both running into stuck looping issue EVENTUALLY so agentic workflow is impossible right now. My system is RTX 4090 + RTX 6000 pro. If I go higher quant to IQ4 I will get garbled text. I have been trying to debug this for the paste two days.

I am also getting similar issues on UD-IQ3_XXS and UD-IQ4_NL. I'm running on a single RTX PRO 6000 and 64GB RAM. It seems to be more easily reproducible if I'm running several sessions at once. With just 1 session, it seems stable for a good while, but it's not guaranteed to not eventually run into it.
