nm eth0 connection



Running updated wheezy on a thinkpad T420i w/ xfce DE.

With great embarrassment, after stoutly defending nm, eth0 no longer
connects. This only happens when I run wheezy. The connection is fine
when I run the other distros on the hdd, squeeze and ubuntu 12.04. 
Under wheezy it also happens when the laptop is hard wired directly to 
the cable modem.  

looking at dmesg
root@localhost:/home/holtzm# tail --lines=50 /var/log/dmesg | grep eth0
[   18.864912] ADDRCONF(NETDEV_UP): eth0: link is not ready

Looking at messages
root@localhost:/var/log# less messages | grep eth0 | less

Notice the difference between 15:13:25 and 15:13:26.

Don't know how to approach trouble shooting this. Any pointers
appreciated.
