Hi After a lot of time being debugged, I found out that it was problem with Marvell Yukon 8053 Gigabit Ethernet.
My install environment is a bit change compare to before. I had 1 server which has 2 NICs, 1 for the external and 1 for the internal. Let's name it dserver and aka-server. Exactly , it's a type of Beowulf. All of my nodes are the same with Marvell Yukon 8053 built-in. When I booted over PXE, it first loaded kernel successfully than stop at "Sending DHCP requests ..... timed out" My tcpdump log said like below, which was the packets sent while loaded kernel image.

---------------------------------------------------------------------------------------- Curiously , I connect 1 of my spare pc (Intel Pro 10/100 Ethernet) to the switch, than boot up. It went with no problem. I could get into shell command. As before , I downloaded lasted driver for Marvell Yukon 8053 (sk98lin ver 8_28)and built it permanently with kernel. Anyone have solution for that. Thank in advance Gavin > regards Thomas > -- Gavin Tran Tsuruoka College of Technology Japan Department of Control and Information Engineering
