eth0: tx queue full

Raana — Fri, 09 Mar 2012 11:27:46 GMT

Hi Friends,

This is my first time to post a queries.

Now i am working on imx51

I have a problem in Ethernet(LAN 8710)

If the Ethernet cable is not connected while booting,and if it connected once after Linux boot "eth0: tx queue full!" error is displayed continuously in the terminal.

Suppose, the Ethernet cable is connected on booting time, am not getting any error...

NOTE:

In my rootfs, I enabled "udhcpc"..

So, it's searching for Ethernet but it's not there...

and also I don't know this is Hardware or Software issue..

If any one knows...Let me know.

Here, I attached my log print.

Thanks in advance

Regards,

J.P.Raana

can you try modify fec.c, fec_timeout as below:

static void fec_timeout(struct net_device *dev) 
{ 
 struct fec_enet_private *fep = netdev_priv(dev); 
 dev->stats.tx_errors++; 
 

 fec_restart(dev, fep->full_duplex);
 

 

 netif_wake_queue(dev); 
}

Hi Raana,

Did the above fec.c change from Yong Huang fix your problem?

Thanks,
