I have an acer 3003LC laptop with Fedora Core 4 installed on it. My usb device driver project requires me to upgrade my kernel to 2.6.15.4. I follow the usual steps of building my kernel. The problem is that when i make multiple kernel images of 2.6.15.4 they fail to co-exist.What this means is that only the last kernel built works properly ie. i'm able to insert my device driver only in the newly built kernel. For all others, the kernel images it says ' invalid module format' upon insmod. What could be the reason for this? I suspect that every time i build the kernel /lib/modules/2.6.15.4 gets overwritten and that is why only the last kernel image works. But what i fail to understand is that even if that is happening why should the kernel say 'invalid module format' coz the difference between the 2 kernel images is merely of 1 or 2 CONFIG parameters in .config file (which are in no way related to my driver). To name them, the options are CONFIG_PREEMT and CONFIG_SMP. Is there a way of having different /lib/module/2.6.15.4 directory structures for 2 kernel images of the same version?
