(Probable Lubomir is subscribed but just in case sending the mail to
him, he made originally the Wiki page and is hosting the patch.)
I just tried that GRUB in qemu debugging with GDB stuff.
The Stuff on that Wiki page is a bit outdated.
I'm not that familiar with such things but maybe I can try to fix this
myself.
Attached is the grub2-gdb.diff updated to current SVN version.
I don't have any webspace to host it.
I have compiled grub2 with CFLAGS="-g3 -O0"
gdb shows:
GNU gdb 6.8-debian
[copyright stuff]
This GDB was configured as "x86_64-linux-gnu".
