Hello,
I am using mini2440 arm board with linux 2.29.4 kernel ported. I can successfully insert the kernel module (main.ko). But when trying rmmod it does not be removed.
###########
[root@FriendlyARM /]# rmmod main.ko
rmmod: chdir(2.6.29.4-FriendlyARM): No such file or directory
[root@FriendlyARM /]# modprobe -r main.ko
modprobe: chdir(2.6.29.4-FriendlyARM): No such file or directory
##########
Please help me to solve the problem.
Thanking You,
Anoob T Murali.

Are you sure there is a module named main.ko?
First check the output of lsmod to see if its there or not, if its not there then its obvious that it will give that error.
use this command to serach main.ko: #lsmod |grep main.ko
The kernel looks for its modules in /lib/modules/`uname -r`/. Likely your kernel and your modules aren't in sync with what arch/release they think they are, likely because they were installed from some (differing) packages. That is, either the kernel or the modules is having an identity crisis. You can avoid the problem totally by building/installing the kernel and its modules from the same source. Remember to run depmod afterwards. Also, modules should be inserted with 'modprobe whatever' and removed with 'modprobe -r whatever'. List all available modules the kernel knows of with 'modprobe -l '.

A module is inserted with insmod using the fileid of the module; which ends with ".ko". However, the fileid is not the module name; which is the fileid minus the ".ko". Try doing a rmmod on just "main". By the way, that is a somewhat dangerous name for a module.
