upgrade to linux 4.0.1-1 breaks r8169 ethernet driver

My recent upgrade from kernel 3.18.6-1 to 4.0.1-1 seems to have caused some problem with my ethernet driver. After upgrade, the ethernet device exists, but the mac address is listed as ff:ff:ff:ff:ff:ff (the broadcast address). Furthermore, dhcpcd fails to set an IP address on the device and even after setting the IP address, routing table, and device state manually the device cannot ping the local router.

anyone else experiencing this issue?

Details below.

Output of lspci -v:

I had a similar issue with a custom kernel. You could try a 3.19 kernel, re-install the kernel from core and/or compile it yourself.

Same issue. I found related discussions here and here.
EDIT: Appeared when upgrading from 4.2.3-1 to 4.2.4-1
