Lite5200 NFS mount issue

Tue Jun 20 18:15:28 EST 2006

Hi all,
I'm using u-boot 1.1.4 (CVS downloaded 2006-05-04) and ELDK 4.0. I've encountered 
problems when trying to mount a NFS root filesystem when using the Lite MPC5200
development board. The system mounts ok when the board is connected to office wide 
network switches but if the board is connected directly through a small 100/10Mbit switch
to the NFS server, the mount halts as shown in the log below (The 100/10Mbit switch
do work as other boards can mount their filesystem through these). Does anyone
recognize this problem and know a suitable work-around/solution?
