[Hatt Tom]

hi:

   uname -a  :  Linux localhost 3.5.0-23-generic #35~precise1-Ubuntu SMP
  The debugpackeg installed is linux-image-3.5.0-23-generic-dbgsym ,

  run  stap-prep script ,it reports：

　　Package linux-image-3.5.0-23-generic-dbgsym version 3.5.0-23.35
               does not match version of currently running kernel:
               3.5.0-23.35~precise1

What should I do to fix this ?

Thanks!
