Believe it not it is actually possible to do so.  I have seen this
happen a lot duel booting windows then linux.  Linux then not wanting to
start the network or the windows machine also.  You need to do a
complete shutdown then power back on for the card to "reset". Or leave
it off a while.  It is a real problem though.  It could also be a fact
that the driver is not doing a complete shutdown also.
