Bug Description

I recently installed Maverick (Ubuntu 10.10) alpha 3 with kernel 2.6.35-14-generic
Under lucid wireless was working fine.
Now it won't associate.
Automatic data collected by ubuntu-bug is booting from old kernel 2.6.32-24-generic-phc which works fine. (Can't report under the new kernel very easily due to lack of network.)
Hardware is intel 5100 -- Lenovo X200
Access point is D-Link DIR-655. (802.11n)
Also failed with other unknown 802.11g access point at my office.
Behavior is the same with and without linux-backports-modules-wireless-maverick-generic
backports package is not required under 2.6.24

Under new kernel (2.6.35), which is broken, syslog has:

Under old kernel (2.6.32), which works, syslog has:

Also, while failing to connect to the unknown router at work (but not to the DIR-655) I got a bunch of these:

Solved this one. In order to make my card work with a previous kernel I needed the following modprobe options:

options iwlagn disable_hw_scan=1 swcrypto50=1 swcrypto=1

With the new kernel this messes it up. But removing the options, everything works fine.

@mycl: I'm having the same issue here, but I couldn't find the file in wich you edited that line.
Was it in /etc/modules ?

rgrep iwlagn /etc/*

gives nothing resembling the line you described.

I have/had a similar problem with the same error messages appearing (see bug #663298).
For me it worked again after I turned on Bluetooth (thanks to Zander Hill for the info).
