Description of problem:
Kernel 3.1.5-1 iwlagn driver used with an Intel Ultimate N WiFi Link 5300 fails to authenticate with a WPA/WPA2 Personal access point. Reverting to kernel 3.1.4-1 fixes the problem.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Try to connect to wireless router using Network Manager.
Failure to connect.
I've attached dmesg, log and wpa_supplicant.log output.

wpa_supplicant log output
Seems there is some kind of regression in iwlagn with 3.1.5:
Indeed, but I would rather expect commit causing breakage is:
> 5c30a5b33f77264cddcfb1a6659d3a9ac2661103 iwlagn: fix HW crypto for TX-only keys
> 43c308bd8d0a3e7d98c5abcd41a4a3fada3d198f iwlwifi: do not re-configure HT40 after associated
Tomorrow I'll provide test kernels and we will see (or maybe intel will provide proper fix in that time :)
Roger, please check if one of these kernels make iwlwifi works in your setup:

The ht40_fix kernel fixes the problem. The revert_hwcrypto one does not. Many thanks for the quick response.
