I think I figured out why rtems_panic was locking up instead of
    shutting down the executive and returning to the code that called
    boot_card().

    Later on there is code to print some messages on the standard error
    stream, a recursive call back to rtems_verror (through rtems_error)
    and finally a call to _exit().

    I think that the _Thread_Disable_dispatch() is preventing the final
    context switch back to the boot_card() code.  Does this sound right
    to you?
