Me too with a workaround (yes, I'm very happy!):

I'm on Lucid with with kernel 2.6.32-22-generic, running an Intel 5100
wifi card and iwlagn driver. I was getting the two minute 'no probe
response' error like the bug creator (see my syslog below). I fixed it
on my machine by disabling IPV6 in the kernel at boot time by adding

ipv6.disable=1

to my kernel boot line in grub, then doing a

sudo update-grub

My wifi has sped up incredibly (speedtest.net showed almost double what
I was getting previously) and the annoying disassociation has stopped
(now I can use Skype without 4 seconds of dropped packets and silence
every 2 minutes).

No guarantees, and obviously if you depend on ipv6 you're kinda stuck,
but maybe it will help somebody track down the issue.
