Qwen 3.6 looping/repetition problem (Tesla p40s and Halo strix)

I've been really liking the Qwen3.6 models, and it does great on simple things. When I try tasks that are high value for me, I run into tool repetition or thinking looping.

I've tried the Qwen3.6 HF settings and the Unsloth suggested settings, and now i'm trying another set.

Anyone have a solid solution worked out?
