Hi,

This bug seems linked to the ARL driver used for the eth0 Ethernet controller: Qualcomm Atheros AR8161 Gigabit Ethernet (rev 08).

It is identified in BugZilla : https://bugzilla.kernel.org/show_bug.cgi?id=70761 as
"Bug 70761 - AR8161 wir alx driver: Randomly stops to receive packets with small MTU"

A palliative solution is to increase MTU size above 8192.

This can be down temporarily with
ifconfig eth0 mtu 9000

Or permanently in network manager.

This palliative solution is effective in my case with kernel 3.19.0-21-generic and I tested it satisfactorily with 4.1.0-040100rc8.
