my eth0 ethernet r8169 with MAC, e.g., ab:cd:ef:gh:ij:kl, normal before 9.10, but abnormal when installed 10.04. There was a new eth1 item, eth1, in /etc/udev/rules.d/70-persistent-net.rules with MAC, 00:00:00:00:ij:kl. It became normal after updating about one month later. But It became 00:00:00:00:ij:kl once again after updating today.
