I am now using compat-wireless-2.6.39-1. I hope, this is new enough (it seems to be from last night anyway...) I now even exchanged the wireless card, now I am using a Gigabyte GN-WI01HT (AR5414 chip), the problem seems to be the same. I attached some dmesg info. Could this be a hardware error of the mainboard? Actually, I only have one hardware to test on and I somehow don't really trust it. Just a thought of mine... What are your suggestions, or could this really be a bug?
