[intrepid] iwlagn freezes system while authenticating to network

[Wiktor Stasiak]

I am using WPA2 authentication in my wifi network. From time to time my wifi looses connection and then I have a 1 second freez (I cannot move mouse) and all my previous connections to internet are dropped.

I am about 4-5 meters from AP and 95-100% signal. No high traffic, max 250kB/s.

I attach dmesg and lspci

I am using Intrepid with "Linux ubuntu 2.6.27-4-generic #1 SMP Mon Sep 22 04:40:15 UTC 2008 x86_64 GNU/Linux"
