The recent update to udev 0.140-1 lead to a system without network access to me. The error messages were:

It seems, the update added rules to /etc/udev/rules.d/70-persistent-net.rules by increasing the device number and applying the last applicable NAME directive instead of the first one. This lead to the following file here:
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="XX:XX:XX:XX:XX:a7", ATTRS{type}=="1", NAME="ath0"
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="XX:XX:XX:XX:XX:18", NAME="eth0"
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="XX:XX:XX:XX:XX:XX", NAME="eth1"
# PCI device 0x10ec:0x8139 (8139too)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="XX:XX:XX:XX:XX:18", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"
# PCI device 0x168c:0x0013 (ath_pci)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="XX:XX:XX:XX:XX:a7", ATTR{type}=="1", KERNEL=="ath*", NAME="ath1"
So the devices created were eth2 and ath1 but /etc/network/interfaces contained entries for eth0 and ath0. So fixed /etc/udev/rules.d/70-persistent-net.rules and rebooted.
<rant>Is it really necessary to break network access with an update???</rant>
Update
I forgot this one: #521521.
