Syslinux - May 2011 - pxelinux.0 tftp kernel vmlinuz transfer hangs on PXE startup

Hello,

       I just would like to let you know that after investigating a 
while, it seems to me that the vmlinuz kernel ( Centos 5.6 Xen ) tftp 
transfer is hanging because there look to be some buffer overflow on the 
client side because after a while ( more or less 50Kb transfer ) , there 
is no more acknoledgment coming back from the client even in the last 
syslinux distribution revision 4.0.4.

       I hope it will help.

       Best Regards

       Pascal KOENIG

Please give as much technical details about your system as you can, as
well as what TFTP server you are using.  A packet trace
(tcpdump/wireshark) would help too.
