Same problem for me with slightly different symptoms (overall network seems OK but perfs are very low and some samba functions does not work like samba printing). When I use the r8168 v8.003.00 from realtek and after I managed to get rid of r8169 (loaded in initrd, so blacklisting seems not working) things get perfectly OK for all network functions.
for those who want to try, here is a little script to replace r8169 by r8168 (after downloading realtek 8168 driver into r8168-8.003.00 directory): #!/bin/sh cd r8168-8.003.00 make clean make mv /lib/modules/`uname -r`/kernel/drivers/net/r8169.ko /lib/modules/`uname -r`/kernel/drivers/net/r8169.ko.old depmod -a mv /boot/initrd.img-`uname -r` /boot/initrd.img-`uname -r`.ubuntu mkinitramfs -o /boot/initrd.img-`uname -r` `uname -r` then reboot... my MB is a GB P35-DS3P and the lspci is provided below.
