Grub2 SVN on 64bit Xserve 2,1

[decoder]

Hello all,


recently, we tried to use Grub2 SVN on a 64bit Apple Xserve (Model 2,1) 
using EFI and after Bean solved some Xserve specific problems that were 
discussed on the Ubuntu forums 
(http://ubuntuforums.org/showthread.php?t=995704) someone else finally 
managed to boot his Xserve 2,1 model with Grub2.

Ours however, did not boot and we isolated the problem to be a memory 
problem: When we plug in 4 GB or more, Grub2 fails (when you finally 
type "boot" on the command line, the machine instantly reboots). If we 
remove all but 2 GB of RAM, it works and we managed to boot a Debian 
kernel. So this seems to be a bug which only appears on this type of 
machine with >= 4GB of RAM.


Unfortunately, I haven't found a way yet to get any debug output for you 
from the machine (serial console doesn't seem to be supported in EFI). 
If there is anything we can do to get this bug solved, please let us know.

If this is the wrong list for this discussion, I'm sorry, I wasn't sure 
which list discusses Grub2 SVN bugs/problems :)



Thanks in advance,
