Comment 16 for bug 845158

please re-test using https://launchpad.net/ubuntu/+source/linux-ti-omap4/3.2.0-1409.12

I belive this bug have been fixed when using the precise 3.2 kernels that contain a reworked arch/arm/mm/fault.c
where this part in do_page_fault:

         * As per x86, we may deadlock here. However, since the kernel only
         * validly references user space from well defined areas of the code,
         * we can bug out early if this is from code which shouldn't.
         */
        if (!down_read_trylock(&mm->mmap_sem)) {
                if (!user_mode(regs) && !search_exception_tables(regs->ARM_pc))
                        goto no_context;
retry:
                down_read(&mm->mmap_sem);

have ben changed to remove the retry: label and goto retry: logic.
