Container network and vzctl enter fail on 042stab120.3

>Description of problem:

Previous kernel (2.6.32-042stab117.16) was working ok, but when booted into 2.6.32-042stab120.3 container does not start properly. Network is not working correctly (external primary ip of container is not pingable, its configured as veth) and `vzctl ente 28r` can not enter to container with `enter into CT 28 failed` message after some timeout. Also, there is dmesg messages appearing:
