[Issue]: v1.0.4 causes NPU hardware crash (0xc00002b6) and Kernel Deadlock on AMD Ryzen AI (v1.0.3 works fine)

[Halthward]

Problem Description

Running any model (even 0.8b) on FastFlowLM v1.0.4 causes a severe NPU hardware disconnect and kernel deadlock. The XRT driver reports 0xc00002b6 (STATUS_DEVICE_REMOVED), indicating the NPU crashed or was forcefully kicked offline by the Windows kernel.
Because the NPU drops offline while memory mapping (mmap) is active, it completely hangs the NTFS file system, causing runlist error and a system-wide deadlock. The flm.exe process becomes an unkillable zombie process (cannot be terminated via taskkill /F), requiring a hard physical reboot.

To Reproduce

System Environment:

OS: Windows 11

Hardware: MECHREVO XINGYAO 15 (AMD Ryzen AI 9 365)

BIOS Version: Updated to the latest official version

AMD IPU Driver: Updated to the latest official Ryzen AI driver

FLM Version: v1.0.4 (Bugged) / v1.0.3 (Works perfectly)

Additional Context (Important Workaround)
I have updated my motherboard BIOS and AMD NPU drivers to the latest versions.
After completely uninstalling v1.0.4, clearing the .flm\models cache, and downgrading to v1.0.3, the exact same model (qwen3.5:9b) runs perfectly stable on the NPU without any crashes or garbage output. This confirms the issue is strictly isolated to the XRT/NPU invocation updates introduced in v1.0.4.

Steps to Reproduce

Environment: AMD Ryzen AI NPU (Tested on MECHREVO XINGYAO Series, Ryzen AI 9 365).

Install FLM v1.0.4.

Run command: flm run qwen3.5:0.8b (Even with --pmode balanced -c 4096).

Type hello.

The terminal throws XRT errors, Ctrl+C fails, and the system deadlocks.
