I would like to add that with 2.6.32 the IP address is dropped even if I exit
the KNetworkManager before unplugging the network cable.

I can reproduce the problem without touching the network cable. If I execute
(I am running Debian 5.0, kernel 2.6.32):

# /etc/init.d/network-manager stop

then the network goes down. After this I execute:

# /etc/init.d/network-manager start

then the network comes up, the IP address assigned by DHCP appears for about a
minute then the this IP address is dropped and the address starting with
169.254 is assigned.

Regards,
