    I have seen that 2.6.30 is out. I'm now running with 2.6.30 and
    tried to crash the ftdi_sio driver, I had no luck till now.

    So it seems to be fixed at least in 2.6.30, and I believe it was this
    patch:

    commit 80193195f87ebca6d7417516d6edeb3969631c15

    Fix oops on close of hot-unplugged FTDI serial converter


    Best regards,
    Martin
