Drat. Thanks very much for checking.

A few directions for that:
- What version of the firmware-iwlwifi package do you have installed?
Is the behavior any different if you update it?
- If you have time for it, please try some kernels halfway between
from the list at  so we can discover which one introduced the
If a 3.0-rc2 or newer kernel reproduces the problem, a log would
also be helpful, since the output for microcode errors was improved.
- You said you are only able to reproduce this with network-manager
and not ifupdown. Can you reproduce it using iw and iproute by hand,
ip link set wlan0 up
iw dev wlan0 connect -w <SSID> key d:0:<key>
This would help us get help from upstream.
