Re: Neighbour Table Overflow on NFS Server

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
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? ----- Original Message ----- From: "Chris Hallinan" <redacted> To: <redacted> Cc: <redacted> Sent: Friday, December 29, 2000 12:46 PM Subject: RE: Neighbour Table Overflow on NFS Serverquoted
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. -Chris Hallinan -----Original Message----- From: owner-linuxppc-embedded@lists.linuxppc.org [mailto:owner-linuxppc-embedded@lists.linuxppc.org]On Behalf Of Mark S.

At the time I think it was cause by a lack of a loopback device and routes. -Mark On Thu, 28 Dec 2000, Cal Erickson wrote:quoted
