Aha, it doestn't seem relevant because you don't have a floppy drive and
you didn't found a place why grub thinks that you have one.
Ok.

It turns out that the file "core.img" does not contain
the string "normal".

Because the file is called device.map
Which means map linux devices to grub devices.

I still assume that, because you even failed to choose the right
severity of this report.
The Debian documentation about this is very clear.

Honourly I don't have still any motivation at all for this report.

Luckly I have already forwarded this to grub-devel and somebody had an
idea.

So now you can proof how much your C knowledge is and your understanding
of GRUB sourcecode.

please add to disk/lvm.c to the mod_init function:
grub_errno = GRUB_ERR_NONE;

please do not forgot to do grub-install /dev/sda or whatever the disk is
you boot from, else the real GRUB isn't updated but of course you know
that.
