The stack dump suggests this is a torchao issue. For RuntimeError: CUDA error: named symbol not found, does it print out what exact symbol is missing? Can you share your installed CUDA version?

It's a torchao issue (see also: https://github.com/pytorch/ao/issues/1110), or more generally a question of expectations whether we should expect BF16 to work on platforms that don't have HW support (see pytorch/issues/124996). On pre-9.0 architecture, PT emulates BF16 (at least for some/most of the kernels), but AO does not for their linear:int4 kernel.
