приехало 2 новых машинки.  на 2 разных метеринках, на 1 3 цфку 9650.. на 
другой lsi9750-8i

И на обоих спустя минут 10 после включение в дмесге появляется вот такое 
вот сообщение (см ниже) и рейды начинают зверски тормозить..по кр мере 
монтирование-отмонтирование происходит секунд 10.  на ядре 2.6.38 
симптомы аналогичные...  Есть способ лечения?
