I am trying to debug module under UML architecture,
i have tried to solve it . But getting stuck where i want to "attach".
Below are the steps taken :
/mnt/space/umlkernel # gdb ./linux
GNU gdb 6.5

This GDB was configured as "i586-suse-linux"...Using host libthread_db
library "/lib/libthread_db.so.1".
(gdb) set args debug=parent gdb-pid=19137
(gdb) show args
Argument list to give program being debugged when it is started is
"debug=parent gdb-pid=19137".
(gdb) att 1
Attaching to program: /mnt/space/umlkernel/linux, process 1
ptrace: Operation not permitted. ******** After this nothing is workable
********
The ps output :
/mnt/space/umlkernel # ps a
PID TTY STAT TIME COMMAND
--- snip-----
19137 pts/1 S+ 0:00 gdb ./linux
19138 pts/2 R+ 0:00 ps a
