## Operating system and hardware support changes
Operating system and hardware support remain unchanged in this release.
ROCm 6.4.1 introduces support for the RDNA4 architecture-based [Radeon AI PRO
R9700](https://www.amd.com/en/products/graphics/workstations/radeon-ai-pro/ai-9000-series/amd-radeon-ai-pro-r9700.html),

### Radeon AI PRO R9700 hangs when running Stable Diffusion 2.1 at batch sizes above four
Radeon AI PRO R9700 GPUs might hang when running [Stable Diffusion
2.1](https://huggingface.co/stabilityai/stable-diffusion-2-1) with batch sizes
greater than four. As a workaround, limit batch sizes to four or fewer. This issue
will be addressed in a future ROCm release.
### RCCL MSCCL initialization failure
When splitting a communicator using `ncclCommSplit` in some GPU configurations, MSCCL initialization can cause a segmentation fault. The recommended workaround is to disable MSCCL with `export RCCL_MSCCL_ENABLE=0`.
