    Stellaris Paul
    Unfortunately if you perform an unlock sequence on that device it will erase the patch that is required at the start of flash. This is listed in the errata for the LM3S9B92 Rev C devices( http://focus.ti.com/lit/er/spmz444e/spmz444e.pdf ). In order to resolve your problem, you will need to issue an RMA...
