Через произвольное количество минут после старта системы отваливается соединение по wifi, рестарт интерфейса не помогает.
kern.log перед этим кишит повторяющимися группами строчек:

Не могу понять в чём проблема,
в данный момент ядро 2.6.38-8
В 10.04 работало без нареканий
Помогите разобраться, если нужен больше кусок лога - просите

Обратил внимание на то, что wifi отваливается только когда ноут работает от батареи, когда от сети - всё ок
