Looks to me that the kernel that u have used is not exporting the schedule function as it does not appear in /proc/ksyms. Hence when u are trying to load a module insmod gives a problem. 2 alternatives to ur solution: (i) Recompile kernel after adding the symbol schedule in file kernel/ksyms.c (ii) Do not call schedule from module. What is this function do_schedule; I do not see this function in my source code? Can u check up with the linux kernel source and check if this is an equivalent function. Regards Raghav Usman's original mail: >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> I am compiling kernel module with a command line cc -D__KERNEL__ -DMODULE -Wall -O2 -g -I. -I/usr/src/linux/include -c -o file1.o file1.c ld -r file1.o file 2.o file3.o modbinary.o Module loads and executes fine. After applying the serial kdb patch (patch applied nicely) and recompiling the kernel, I was getting lot of unresolved symbols, which I understood was due to MODVERSION bug. I have over come the problem. However now I am getting only one unresolved symbol [root@karachi]# insmod modbinary.o modbinary.o: unresolved symbol schedule when I do, I get [root@karachi /root]# cat /proc/ksyms | grep schedule c0122900 schedule_task_R2d6c3d04 c0122b20 flush_scheduled_tasks_R7c3242b4 c01150f0 do_schedule_R26171012 c0109318 kern_schedule_Rb32aaa1b c0115030 schedule_timeout_R17d59d01 c0203540 tcp_tw_deschedule_Rae427462 I donot see schedule() function in the list above, even though this is from schd.c file. What can I do to resolve this problem. Usman __________________________________________________ Do You Yahoo!? Send FREE video emails in Yahoo!
