Comment 33 for bug 769927

I have found that scatter/gather NIC features on server can affect the behavor described above - just disabled them on server:

# my primary iface is eth1.
# here below is a stanza in a server host "interfaces" config
# that requires ethtool be installed
# the same as "ethtool -K eth1 sg on"
auto eth1
iface eth1 inet manual
           offload-sg off

I am not sure that this can fix a problem or simply hide, please test it on your servers and respond. But surely, fix does not affect client side, and excuse hard kernel oop reaction to error in packets from server connections.
