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.
