kernel crashes when ping from VM

[Abhishek Jain]

Hi Team

I'm running ARM 64 as a compute node (4.0.4 kernel version) with contrail vrouter-agent running on it.The compute node is able to make connection to the controller node and I'm able to launch VM on compute node from the controller node(Opencontrail) GUI.

The VM on compute node is able obtain IP address from the virtual DHCP server running on controller node.However I'm facing kernel crash when I'm pinging the virtual GW from the VM.

I'm using the latest opencontrail code.I'm getting kernel crash at function vr_flush_entry at below line..

  swapped = __sync_bool_compare_and_swap(&fe->fe_hold_list, vfq, NULL);

Please help me regarding this.

--Thanks
