nope, that didnt have any effect. I have another theory: i had a
network-intense stress-test going on in the past few hours on the same
network (not involving the laptop) and i stopped it recently. Perhaps
that network-intense test also produced periodic broadcast packets that
got the e1000 out of its weird state before the tx timeout could hit.
Now that i've stopped the test, the network is quiescent again and the
e1000 hangs.
