Have you tried cycling your ethernet on the server side and nfs server
with
ifdown eth0
ifup eth0
or
service nfs restart?
You can also ping your server from another machine to verify that it's
alive.
Hope that helps,

Hi,
I download the kernel 2.6.18 from
http://source.mvista.com/git/?p=linux-davinci-2.6.git;a=summary.
This version and upper start to support ZyDas 1211b based WiFi
dongle. I
build this kernel with davinci_evm_dm644x_defconfig.
I use the NFS as the root file system. Following is my bootargs:
bootargs=console=ttyS0,115200n8 noinitrd rw
ip=10.100.8.21:192.168.1.22:10.100.8.1:255.255.254.0 root=/dev/nfs
nfsroot=10.100.8.76:/home/xrchen/target/,nolock mem=120M
video=dm64xxfb:output=pal
I have 2.6.10 work on dvevm and current root file system also works
well. So
I rebuild the kernel 2.6.18 and try to use the same root file system.
When get into u-boot, I've tried following commands:
1. tftp 80700000 uImage.2.6.18
2. using upper bootargs
But I get following error message:

It seems unable to mount VFS. After several tries, finally I get
kernel
panic.
Could any kind guy help me? Just give some hint is very appreciated.
