Please look at issue #240648, we find the updated R8169.c driver will fail to load after system go to S4 for 3 or 4 times. And eth0 will disappear.
I tested it with same platform I reported this issue(223656) and checked with latest latest 2.6.24-19-generic kernel. And still can find this issue.
By looking at dmesg, during the driver loading, IRQ is failed to allocate for this NIC card and cause the NIC initiate fail after system resume from S4.
