[syslinux] mboot.c32 loses connection when loading the Kernel

[Philipp Fehre]

Hi,
I'm hope I'm right here.
I'm trying to boot a XEN 3.2.1 via PXEBoot using the following config:

LABEL xen_3.2_amd64
         kernel mboot.c32
         append images/debian/xen_3.2/amd64/xen-3.2-1-amd64.gz  \
		 ---  images/debian/xen_3.2/amd64/vmlinuz-2.6.26-bpo.1-xen-amd64 rw  
root=/dev/nfs nfsroot=172.16.0.1:/var/lib/tftpboot/clientroot panic=0 \
		 --- images/debian/xen_3.2/amd64/initrd.img-2.6.26-bpo.1-xen-amd64

Its an AMD64 Machine, and the PXEBoot works using the Debian Netboot  
Images to Test.

Looking at the Machine Booting I get the Message that mboot.c32 is  
loading the Kernel but then it stops.

I ran tcpdump to check what happens and I first get Messages that the  
Client Machine Requests the Kernel, the Server Answers and sents the  
first couple packages,
but then I seems to lose the Connection and starts to sent ARP  
Requests looking for the Client Machine which won't get answered,  
therefor boot hangs.

Looking at the Mailing list I found a Message that somebody had the  
same Problem with mboot.c32 form Version 2.xx and the suggestion was  
to try a newer Version. I'm using Syslinux 3.31 (from debian stable),  
so I guess it should be new enough.

Now I'm kind of stuck.

Hoping for any Ideas,
	Phil
