В ovz есть одно подозрительное изменение в драйвере e1000 - commit
2d46cb1712da0b94652c94f8bb9bac662c10d847:

    e1000: fix initialization of irqs
    
    In case of irqpoll boot option set, e1000 may oops due to:
     1) e1000 register it's handler with e1000_request_irq;
     2) spurious interrupt happens;
     3) kernel tries to handle this interrupt with all available descs;
     4) e1000_intr is called and oops due to not initialized clean_rx handler,
        because e1000_up is not called yet.
    
    Solution is to initialize driver before handler registration.

Возможно, этот патч ошибочен - во всяком случае, мантейнер драйвера
e1000 его забраковал:
