Wired disconnects due to add_object(): Netlink error adding 0.0.0.0/0

I have a Lenovo Thinkpad E540 with r8169 wired onboard networking. After 15-30 minutes use the network stops working. There are no messages in dmesg, link stays up etc.

This is output to journal:

Disconnecting and reconnecting the cable solves the issue until next reboot, so I don't think it's a DHCP configuration issue. Other PC's on the network work fine.

This has also been reported as kernel bug #1459985 as it's still unknown what causes the issue.
