Hi ! I have downloaded a kernel 2.2.10, and patched it with RTlinux Beta11, I compiled the kernel and the modules, and in rtl directory, I run" make all" and " make install".After reboot, everything seemed ok, but when I wanted to load the RTlinux modules: rtl_time,rtl_sched,rtl_fifo, some errors like "unresolved symbols xxx" happened. insmod rtl_time "unresolved symbol _sti unresolved symbol get_tsc_quotient unresolved symbol rtl_request_global_irq unresolved symbol rtl_hard_enable_irq unresolved symbol rtl_free_global_irq unresolved symbol rtl_global_pend_irq unresolved symbol kd_mksound unresolved symbol _cli " "insmod rtl_sched" and "insmod rtl_fifo" get the similar results , I have read privious mail about this problem in this group, and the answer is " the order of modules is important", but whatever load order of the three modules I have tried, I get the same errors, why this happen? Any help is appreciated.
