NETDEV WATCHDOG: eth*: transmit timed out

This is error occur when ever the network interface is hanged, It has something to do with TCP Segmentation Offload (TSO)

below steps is the workaround and it has solved the problem.


1. rebooted the server in single use mode
2. restarted the network interface and started the server in normal mode
3. ethtool -K eth0 tso off

If the network interface is configured as bound or Team.. then reconfigure it.
