What is the issue?

Hello,

When I run tinyllama model with a simple prompt, it works.

However, when I run gpt-oss or deekseek-r1 model with the same prompt, I get a failure.

$ ollama run deepseek-r1 --verbose
>>> how's it going?
Error: 500 Internal Server Error: model runner has unexpectedly stopped, this may be due to resource limitations or an internal error, check ollama server logs for details

Hardware and OS:

OS: CachyOS x86_64
Host: HP OmniBook Ultra Laptop 14-fd0xxx (SBKPF)
Kernel: Linux 6.17.7-5-cachyos
Shell: zsh 5.9
Terminal: kitty 0.44.0
CPU: AMD Ryzen AI 9 365 (20) @ 5.09 GHz
GPU: AMD Radeon 890M Graphics [Integrated]
Memory: 5.08 GiB / 30.65 GiB (17%)
Swap: 516.00 KiB / 30.65 GiB (0%)

I am running the ollama-vulkan package.

I’d like to report that the same panic: failed to sample token error also occurs in an environment different from the one previously mentioned.
In my setup—Windows running on an Intel Arc GPU—the issue appears only when using the gemma3:27b model. It does not occur with gemma3:12b, gpt-oss:20b, or deepseek-r1:32b.

PS C:\WINDOWS\system32> ollama run gemma3:27b --verbose
>>> how's it going?
Error: 500 Internal Server Error: model runner has unexpectedly stopped, this may be due to resource limitations or an internal error, check ollama server logs for details

PS C:\WINDOWS\system32> ollama run gemma3:12b --verbose
>>> how's it going?
It's going well, thanks for asking! As an AI, I don't *feel* things, but my systems are running smoothly and I'm
ready to help. 😊

How about you? How's it going with you?

The user asks "how's it going?" This is a casual greeting. We should respond friendly, maybe mention we are here
to help. Probably brief.
...done thinking.

<!-- gh-comment-id:3541836732 --> @y-hattori commented on GitHub (Nov 17, 2025): I’d like to report that the same `panic: failed to sample token` error also occurs in an environment different from the one previously mentioned. In my setup—Windows running on an Intel Arc GPU—the issue appears only when using the `gemma3:27b` model. It does **not** occur with `gemma3:12b`, `gpt-oss:20b`, or `deepseek-r1:32b`. ``` PS C:\WINDOWS\system32> ollama run gemma3:27b --verbose >>> how's it going?
