    Subjectoops on rmmod of rtl8192ce
    From
    Every so often on resume my rtl8192ce stops working, it can see APs
    but won't attach to any of them,

    I see 3 probes, then a direct probe timeout message. If I s/r a few
    times sometimes it comes back. This time I tried to rmmod rtl8192ce
    and got a nice oops.
