$ cargo --version
cargo 1.77.1

$ rustc --version
rustc 1.77.2 (25ef9e3d8 2024-04-09) (built from a source tarball)

Experienced on a NiXium's system https://github.com/NiXium-org/NiXium/tree/41a245009dc543c08ed7dd0b3be55958b6921167/src/nixos/machines/tupac using devshell https://github.com/Kreyren/firmware-open/blob/e469d5a7e1b17154dbceacc3b27ffbfd631e05c9/flake.nix

To get the same environment install nix and run nix --extra-experimental-features 'nix-command flakes' shell 'github:kreyren/firmware-open/1ba6a0f7d07363bf70ea4f8ebf7e96730b52176b#devShells.x86_64-linux.default'

It doesn't seem to be an issue on the system side as /dev/mem is readable from root.
