Hello,
I have been debugging my custom 823 board. I have an NFS Server setup on
which my kernel on the board mounts. I have using this server without any
problems for more than a month. All of the sudden, my NFS Server complains
of "Neighbour Table overflow" . The NFS Server was not modified, nor
restarted. The error also says that the Server returned error -5. Can
someone suggest any remedy for this problem?
Sincerely,
Navin Boppuri

Navin,
The message "neighbour table overflow" is the result of some
changes to the IP stack software in Linux version 2.2.x +. This
simply means that you are unable to connect to your NFS
server. It may be related to the driver, but it may also be
related to other issues, such as NFS server not running or
incorrectly installed, no physical connectivity to NFS server,
etc. Check the configuration of your NFS server and IP
network before diving into the driver.

Hello,
Have you recompiled your kernel lately? You might have changed the
SCC number for your Ethernet interface by accident. I did this once and
went nuts trying to figure out what was wrong. Try changing it and see if
it works. If not change it back and continue to go nuts. ;-)
Good Luck

I may be completely off-base here, but I seem to recall getting some of
these a long time ago. At the time I think it was cause by a lack of a
loopback device and routes.

Hello again,
I forgot to mention something. I sniffed the ethernet packets on the NFS
Server machine. I see that a request comes in from my custom board to the
NFS to the correct IP of the server. The HW Address of the board shows up
correctly, but the HW Address of the Server in the request shows up an 0.
ARP:
Request from:
211.111.21.41 --> 08:09:87:l0:73:16 // ethernet info of the custom
board
211.111.21.43 --> 00:00:00:00:00:00 // ethernet info of the nfs server
Does this look like some ARP problem? I am not sure about that since my TFTP
request for the zImage works just fine and the arp tables in the server show
up the board info correctly.
Any ideas?

Can't say I know exactly what it means (internally to the
kernel/driver) but we ALWAYS get this message when the
Ethernet cable is disconnected. I would suspect physical
connections: check your cable,hub, etc. In our experience,
it seems to indicate that the Ethernet driver is incapable
of completing transmit operations.

Hello,
I seem to have solved my problem. I was working on some driver and while I
was setting up the interrupt stuff, I set up a wrong Interrupt Level, which,
I guess, was being used by the ethernet driver . This messed up the ethernet
driver and so the problems. I apologize to everyone for this. I appreciate
all the answers. I am totally new at writing drivers and hence, the hiccups.
Sincerely,
Navin Boppuri
