NETDEV WATCHDOG: eth0: transmit timed out

Post by johan »

Hi,

I've had my fit pc2 for almost a year now but recently it has been printing the following message in the dmesg output:

NETDEV WATCHDOG: eth0: transmit timed out
r8169: eth0: link up

Whenever this happens, the network traffic to/from the fit-pc2 stalls. I'm running Debian Lenny on it with kernel 2.6.26-2-686. Does the message above indicate a hardware error with the NIC? Has anyone else had the same problem before perhaps? Is there anything else I could try to find out the cause of this problem?

Any help, hint, tips are welcome.

Thanks,

Johan

You may want to ensure that the problem is not with your network gear - for example by connecting directly to another computer (no need for cross cable, there is auto detection of TX/RX) and running some traffic.

Also, if something has changed recently with your software setup, this could affect Ethernet behavior.

I suggest before RMA, try to reproduce the problem with the software setup supported by CompuLab - e.g. Ubuntu 9.10

There are some posts and even a bug report for this behavior, but it should have been fixed by now. Interesting, that this happens after working well for quite some time. You might want to check [1], [2] and [3].
