Fix in newer e1000 drivers.  Your failing request_irq().  Need to remove
some code in e1000_up so we don't try to free resources twice:

        if(request_irq(netdev->irq, &e1000_intr, SA_SHIRQ |
SA_SAMPLE_RANDOM,
                       netdev->name, netdev)) {
-               e1000_reset_hw(&adapter->hw);
-               e1000_free_tx_resources(adapter);
-               e1000_free_rx_resources(adapter);
                return -1;
        }
