The kernel fails to probe for the network, so it's unlikely that this
has anything to do with issues in NetworkManager. Could you please
provide debug logs for wpasupplicant?
You can get those by running:
sudo python /usr/lib/NetworkManager/debug-helper.py --wpa debug
Before reproducing the connection attempt. Logs will be in
/var/log/syslog; which you can then attach to this bug report.
Thanks!

Title:
NM disconnects from 802.1x network shortly after authenticating --
Intel PRO/Wireless 5100 iwlwifi
Status in “linux” package in Ubuntu:
Confirmed
Status in “network-manager” package in Ubuntu:
Incomplete
Status in “wpasupplicant” package in Ubuntu:
Incomplete
Bug description:
Very similar to bug 548992, following post at bottom requesting
separate submissions for new occurances.
"iwconfig wlan0 power off" fails to fix the problem.
Similar problem here:
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2305
In that post, suggested that the problem lies in
supplicant/dhclient/dhcpcd
Please let me know if any other information or logs are required. I
have a pretty substantial supplicant / nm syslog tail attached while I
go through the whole shebang (with funny notes!).
Cheers all.
