Thanks.  Can you spell it out more for me?  What kernel did you test
from squeeze (you can get the installed kernel version with

	dpkg-query -W linux-image-$(uname -r)

and the version number of the running kernel is in parentheses in

	cat /proc/version

output)?  What authentication scheme are you using (WEP, WPA, or
something else)?  What is your wireless chip and other hardware
configuration (full "dmesg" output from booting and reproducing the
problem would be helpful).  Can you reproduce it using iproute and iw,
like so:

	ip link set wlan0 up
	iw dev wlan0 scan
	iw dev wlan0 connect -w <ssid> key d:0:<key>
	dhclient wlan0

Does installing the crda package from wheezy (I haven't checked if it
can be installed in squeeze without too much surgery) or upstream make
things any better or worse?  If you have time to try it, could you
bisect through the pre-compiled kernels in-between listed at
http://snapshot.debian.org/package/linux-2.6/ to find which one fixes
the bug?  Does an iw event log retrieved as described at [1] reveal
anything interesting?

Hope that helps,
Jonathan
