Struggling to get function kernel running

[DecrepitHuman]

This is my first project using this crate, I've followed the quick start (https://github.com/rust-osdev/bootloader/blob/HEAD/docs/create-disk-image.md) exactly down to the file/folder names. The project generates both uefi.img and bios.img files which QEMU accepts, but after loading the kernel I can see "Third Stage (....)" in the console, but it immediately closes and restarts the kernel. The entry point (using the entry_point!() macro) has a infinite loop and so does the panic handler, which I would assume would leave the kernel "hanging" but instead constantly restarts as if the kernel's code isn't running at all.

That document doesn't explains how to add something useful to the kernel. Have you really got a kernel? If you don't have one, the bootloader will automatically enter in panic. And QEMU will handle it rebooting the system.

I'm currently working on a more detailed guide for the upcoming third edition of os.phil-opp.com. The latest draft is available at https://github.com/phil-opp/blog_os/blob/edition-3/blog/content/edition-3/posts/02-booting/index.md. Could you try whether this fixes your issues?
