I can confirm this bug on a Dell XPS1330 Ubuntu Intrepid Linux **** 2.6.27-11-generic #1 SMP Thu Jan 29 19:24:39 UTC 2009 i686 GNU/Linux the strange thing is this bug only occurs with certain Accesspoints e.g. Cisco >From time to time it using the wireless with those ap s even causes complete >system hang. I'm using a vpn-connection (cisco - vpn with vpnc) on top of the wireless connection.
Let me know if you need further details.
