Running Pytorch with some models (Qwen-Image-Edit-2509) can result in a
hang that occurs in the MES scheduler.
amdgpu: MES failed to respond to msg=SUSPEND
Upstream fixes linked below, as well as the Ubuntu 6.14 patch recently
accepted.
AMD ROCm 7.0.2 is supported on Debian 13, so this bug impacts a
preferred use case for headless operation to maximize unified memory for
large models. (Strix Halo 128GB)
