How did you allocate this buffer?  Is is system RAM?  If it's system RAM,
did you use kmalloc, vmalloc or __get_free_pages. (kmalloc, vmalloc usually
do not work, you have to use __get_free_pages).

Hi Tony, yeah , I use __get_free_pages : (this function is called in int 
init_module(void) )

Hmm, I don't see anything obviously wrong with the code.  Maybe you can
post this at the ARM mailing list (linux-arm-kernel@lists.arm.linux.org.uk).
