This one can't happen because of the race conditions are avoided
by the use of cep->lock.

What driver are you using? That line of code hasn't been in a driver
for a very long time. This was a very obvious bug that has been
corrected long ago. You should be using the FSM Labs linuxppc_2_5
bitkeeper tree for any of the 8xx/82xx development. There are lots
of things that were placed in the 2_5 tree when the 2.4 tree was frozen.
We are now trying to merge them back, but there are still some pieces
left to go.
