I seem to be seeing the same problem on:

The hang messages started after I rebooted into Jessie's kernel. Previously
the machine had been perfectly happy for years with Wheezy's kernel. The
machine has a second Realtek NIC that continues to work normally.
After a few days of messages like this they increased in frequency and the
network interface just stopped working altogether. After a reboot the
network interface worked again but the messages came back:

At that point as a stab in the dark I ran:
ethtool -K eth-office tso off
and the network has been reliable and no such messages have appeared since
(about 24 hours.)
