JH7110_visionfive2_upstream: store (or AMO) access fault

[SeTSeR]

On NixOS with latest upstream kernel without additional patches every Nix command, such as nix build nixpkgs#verilog, leads to kernel panic with the following trace:

I believe the problem is pretty old, I encountered it in upstream kernels several times last year. Kernel is built with GCC 12.3.

@SeTSeR Does it happen with the latest 6.9 relese in nixpkgs-unstable? Would you know how to fix NixOS/nixos-hardware#958?

[onny]

How did you run mainline kernel with NixOS?

[SeTSeR]

How did you run mainline kernel with NixOS?

I didn't run mainline kernel, just the kernel from branch with preparations for upstream. I run it using boot.kernelPackages option. As for latest kernel for nixos-unstable, I did not try it, but it appears to be unbootable for now.
