Syslinux - Dec 2008 - mboot.c32 loses connection when loading the Kernel

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

3.31 is quite old.  The current version is 3.72.

Capture the network packets once again,
put the libpcap[0] file somewhere on-line
and post the URL of it to the mailinglist.

Geert Stappers
willing to take a closer look at the captured packets

[0] the format of wireshark and tcpdump
