Bug Description

Tonight I updated my 12.04 install with the latest kernel image (linux-image-3.2.0-12-generic). After a reboot, my network card couldn't connect to my wireless router. Tried rebooting a couple of times without success. Removed network definition and tried re-adding but couldn't get it to work. Booting back into the 3.2.0-11 kernal allows the network card to connect.

Problem seems to be with the DHCP. Dhclient is unable to get a response to a DHCPDISCOVER or a DHCPREQUEST call. Here are the relevant lines from the syslog:
