Hi,
I'm having problems with the startup code for my toy kernel for amd64 that
switches from 32bit mode to 64bit mode and I'm at a loss how to debug this.
The code used to work last year (with qemu-kvm 0.14.0) but fails now with
QEMU emulator version 1.1.0 (Debian 1.1.0+dfsg-1).
Has something

Description: Allow 64bit elf binaries in multiboot format
This patch allows 64bit elf files with multiboot header to be loaded.
The entry point will still be called
be called in 32bit mode and the kernel
must switch to 64bit mode on its own. The image and all modules must
also be located in the lower 2GB of ram. All the restrictions of a
32bit image still apply.

Hi,
I've been looking into the multiboot2 specs and started to implement
them for kvm for Debian. If anyone wants to try them out or help
complete support for them I've uploaded a first patch and example kernel
to the Debian BTS [1]. The kernel boots but only the essential features
are there yet.
