* for unmasking the RTC alarm and Timestamp interrupts (features not in hal) and for the serial console buffer, which I guess I should update but I'm pretty sure it isn't causing the problem.

```
let runner = Runner::new(
        ROOT_MENU,
        unsafe { &mut *ptr::addr_of_mut!(MENU_BUFFER) }, 
        tx,
        &mut menu_context,
    );
```
