E1000e does in e1000_netpoll():
disable_irq(adapter->pdev->irq); ... enable_irq(adapter->pdev->irq);
The network card interrupt is rerouted to a legacy interrupt on irq_disable(), in your case irq 19.
Sigh, there is not much we can do about that...
@Jon: Any idea ? Can you please gather some more info about that oddity. It will come back... :(
