It seems to work. I connected and disconnected it a bunch of times (due to
a somewhat flaky connector) and mounted it, wrote to it, had it disconnect
itself, and mounted it and ejected it, and generated some memory load, and
got no oopses. (Just to be clear, I was testing the 0001 and 0003 of the
first attempt with the formerly-attached patch as 0002, replacing the
original 0002.)
