GRUB Error 16: Inconsistent filesystem structure when try toload core in Genode/NOVA demo

Fri Nov 2 20:35:10 CET 2012

1 - menu.lst - I can either include it in-line or as an attachment
    (I hate to pound the mailing list with it) - I do not have a
     place to post it at the moment.
2 - yes to all.  The Genode and kernel binaries are on the same harddisk
    as /boot/grub/menu.lst.
3 - all binaries in same partition, including (just for completeness)
    the vmlinuz-* kernels.
    all same filesystem
    filesystem is ext4

The hypervisor (NOVA) loads OK, so it is being found.
Legacy GRUB halts with the error when it starts to
load the core.
The menu.lst code is based on a template in Genode
documentation.
The specific section preceded by the primary Linux
section is this:
title		Ubuntu 12.04.1 LTS, kernel 3.2.0-32-generic-pae

Hello,

can you please put your grub menu.lst configurations somewhere and post
a link, so we can have a look.

Do I understand it correctly, that you want to add a grub boot entry to
an existing Linux installation ? That means that the Genode and Kernel
binaries are located somewhere on a harddisk and not on a CDROM/ISO
image anymore ?

If yes, are the kernel binary and the Genode binaries located on the
same partition of the harddisk or they are on potential different
partitions ? Do they have the same filesystem type ? Which filesystem
you are using ?

Cheers,

Alex.
