На сервер наставлен CentOS 4-й, сейчас ядро kernel-2.6.9-34.0.1.EL (с ранними тоже самое). После длительной работы (2..6 недель) получаем на консоль:

На этом функионирование системы заканчивается, приходится тыкать "сброс".
Кусок dmesg:

В нём смущают "IRQ routing conflict for 0000:03:06.0, have irq 11, want irq 5", "sym0: handling phase mismatch from SCRIPTS.".

Может, всё-таки кто-то знает, как забороть сие?
