        [Leif Svalgaard]  Thanks, I get the error when I (for testing
purposes) change
        QSECURITY from 40 t0 50, then IPL. After manual re-IPL, the error
goes
        away. When I later go back to 40, no error, then back up to 50, the
        B900 37F0 error comes back (once). I was wondering if I was doing
        something wrong, but I'm not very concerned because - as I said -
        the error goes away. It is just a pain to do manual IPL.
