Public bug reported: Occasionally the onboard gigabit Ethernet on this Gigabyte GA-P35-DS3R rev 1.0 motherboard doesn't work after suspend. This happens less than one out of ten times. Over the last several Ubuntu releases, "sudo ifconfig eth0 down" followed by "sudo ifconfig eth0 up" has always been enough to re-establish connectivity. A long time ago, I sometimes had to unload and reload the r8169 module. This was the first time this bug happened in Ubuntu 15.04.
A similar bug already exists at https://bugs.launchpad.net/linux/+bug/771857 . I am reporting this here because the last comment there asks for a report via "ubuntu-bug linux". Right now, as a workaround, I'm installing the r8168-dkms package, which includes the proprietary Realtek driver.
