Overview

I have installed version b8757, but versions are b9500+ getting crushed with Vulkan inference. Cpu inference is working.

Tested on AMD Ryzen 7 7840HS (Radeon 780M), Qwen3.5-9B-Q4_K_M, Windows 11.

I (sincerely to say, deepseek) found that problem caused by #23687 and crash fixed for intel gpu in 4d8cc0c

Requirements

  • I have read and agree with the contributing guidelines
  • AI usage disclosure: deepseek found that problem, when llama-server crashed and suggest that fix.

Open an issue instead, this isn't any kind of valid solution.
