виснет комп

debian 5 netinstall 2.26.2-686
мать Intel D945GCLF2(D)
сегодня первый раз за 2 недели повис комп
на волшебные клавиши ядро не реагировало
вот что нашел в журнале syslog`a
данное сообщение повторяется раз в 2 минуты с 9 до 10-30
потом комп повис
после перезагрузки пока ничего похожего в логах не появилось
