sunrpc: add cleanup hook call_status() can go to the sleep: .... switch(status) { case -EHOSTDOWN: case -EHOSTUNREACH: case -ENETUNREACH: /* * Delay any retries for 3 seconds, then handle as if it * were a timeout. */ rpc_delay(task, 3*HZ); case -ETIMEDOUT: task->tk_action = call_timeout; .... Task after some delay will be waked up and try access to loopback device. Then do VE stop, fini_ve_netdev() removes loopback device. It can lead to NULL pointer dereference. So try to force kill all VE's live rpc tasks then do VE stop. http://bugzilla.openvz.org/show_bug.cgi?id=726
