Hi
 all

   i did the same, what u told.
     i removed the  -O2 option in CFLAGS and compiled my code.
    now its giving error that  the  unresoved symblos regd schedulre
finction names,
    when i am trying to insert my module in to the kernel.
    prevoiusly it didn't give any error.

    and i ghave one more doubt that, can i use the debugger( rtl_debug.o)
directly for every  module programme.
    or i have to compile the debugger along with perticular module each
time.
    i mean to set archtecture links and all? what is given in the debugger
directory example hello programme.


Thanks

chandu
