debug with gdbstub

hi:)

   I am using gdbstub to debug kernel with gdb side ,communicating with remote protocol.

   I can not solve my problem ,described as below:

      When paging switch is off,at the gdb side ,the data stream from address 0x100055 is :

      0xeb    0x00    0xb8    0x5e    0x00    0x10    0xc0    0xff, these data are right!
    
      But after switch the paging on , at the gdb side ,the data stream from address 0x100055 change to:

      0xc0  0xc0 0xc0 0xc0 0xc0 0xc0 0xc0 0xc0 , these data are wrong.

   I  suspect this linear address is not right dealed with. Is there  advice here?


thanks!
