Maybe it's another kernel regression with Intel NIC and TSO
so you can try this :

# tso => tcp-segmentation-offload
# gso => generic-segmentation-offload
# gro => generic-receive-offload
# sg => scatter-gather
# ufo => udp-fragmentation-offload (Cannot change)
# lro => large-receive-offload (Cannot change)
ethtool -K em1 tso off gso off gro off sg off
ethtool -K em2 tso off gso off gro off sg off
ethtool -K em3 tso off gso off gro off sg off
ethtool -K em4 tso off gso off gro off sg off
# ethtool -K eth0 tso off gso off gro off sg off
# ...

Add this to each iface in /etc/network/interfaces
pre-up /sbin/ethtool -K $IFACE tso off gso off gro off sg off || true
