I seeing regression in iwlwifi using intel 5300 card. It used to work fine but after one upgrade is started to fail. Symptom: at some point card stops transmitting or receiving any data, but still holds connection. No specific errors in logs. Disconnecting/reconnecting helps for very short period. I was able to track it down and it looks like the problem was introduced in next-20111222. I.e. next-20111221 is fine, next-20111222 is not (compat-wireless-2011-12-18 is fine, 2011-12-23 is broken). I tried to look into diff between next-20111221 and next-20111222 but it looks quite large and I do not really know how to bisect it further. So I'd appreciate any hint on this. I'd be happy to provide any additional information and can try patches locally. Thanks! -- Truthfully yours, Martynov Nikolay. Email: mar.kolya@gmail.com
