Problem summary

  • System crash with following stack when dupmsg called from
    a process:
    
     F1000000C01E06CC pse:dupb+00000C (000000006963E93E  ?? )
     F1000000C01E05DC pse:dupmsg+00001C (??)

     0000386C ovlya_addr_sc_flih_main+00014C ()
    

Problem conclusion

  • Code is modified to change dupmsg as kernel service. The
    function dupmsg is not exported as system call to the user.
    This prevents the system crash.
