NFS failed in linux-2.6-virtex tree for xilinx ML403

[Ming Liu]

Dear Grant,
I am bringing up your linux-2.6-virtex tree. However the following problem 
happened:

eth0: XTemac: speed set to 1000Mb/s
eth0: XTemac: Send Threshold = 16, Receive Threshold = 2
eth0: XTemac: Send Wait bound = 1, Receive Wait bound = 1
IP-Config: Complete:
      device=eth0, addr=192.168.0.4, mask=255.255.255.0, gw=192.168.0.3,
     host=192.168.0.4, domain=, nis-domain=(none),
     bootserver=192.168.0.3, rootserver=192.168.0.3, rootpath=
Looking up port of RPC 100003/2 on 192.168.0.3

VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Cannot open root device "nfs" or unknown-block(2,0)
Please append a correct "root=" boot option; here are the available 
partitions:
fe00     509544 xsa (driver?)
  fe01      98248 xsa1
  fe02     402192 xsa2
1f00       8192 mtdblock0 (driver?)
Kernel panic - not syncing: VFS: Unable to mount root fs on 
unknown-block(2,0)
Rebooting in 180 seconds..

My CMD_LINE is "root=/dev/nfs 
nfsaddrs=192.168.0.4:192.168.0.3:192.168.0.3:255.255.255.0 rw 
nfsroot=192.168.0.3:/home/mingliu/ml403_rootfs console=ttyS0,9600 mem=32M"

First of all, I can exclude the problem of my host PC, because the old 
2.6.10 version could run with nfs and root directory mounted successfully. 
So what's wrong with the NFS support in the new kernel? It's quite strange 
that in the information above, why "mount: server 0.0.0.16 not responding", 
rather than the server of 192.168.0.3 which should be there? Do you have 
any hint? Thanks a lot in advance.

Best Regards
Ming
