Here is a better one.
[E1000]: Restore netif_poll_enable call but make sure IRQs are off
This restores the previously removed netif_poll_enable call in
e1000_open. It's needed on all but the first call to e1000_open
for a NIC as e1000_close always calls netif_poll_disable.
netif_poll_enable can only be called safely if no polls have been
scheduled. This should be the case as long as we don't enter our
IRQ handler.
In order to guarantee this we explicitly disable IRQs as early
as possible when we're probing the NIC.

Ack!
this also fixes all the issues we had seen ourselves. I took a bit of time to
get our labs to test it.
Who can pick this patch up for us? Jeff ?
