NetworkManager doesn't work on eth0 anymore

NetworkManager stopped connecting via eth0. Wireless still works, wired
worked before the updates, as "auto eth0" or something like that. Now
there is no such option, and everything regarding eth0 in the
configuration gui is greyed out.

When I plug in the network cable, /var/log/messages says that famous
cryptic message that NM changed state from 2 to 3 and such, and that's it.
No activity regarding dhcp or other usual stuff.

If I setup system-config-network to turn off "conntroled by NM" switch for
eth0 and do a service network restart, the wired network starts to work
correctly, so it is not a hardware problem.

Does anybody know the cause of the problem and a possible fix/workaround?
Up to now NM worked flawlessly on my laptop for both wired and wireless
and I find it more convenient than the old network service, but...

Best, :-)
