[uml-user] uml and gdb debugging questions

Hi,   I have several problems about uml-2.6.17 and gdb debugging.   I start "gdb uml", "b sys_init_module", then "run", but gdb is not break at sys_init_module() when I insmod LKM? Why? How can I do it?     When I type control-c in gdb, the virtual console xterm is also close
