Please is there a way to fix this? Thanks

When you boot your system the kernel is loaded into ram as part of a ramdisk, when you replace the kernel, either with a vanilla or one from suse your system map and modules are also replaced, so when the old kernel tries to do something that requires components not compiled into it, and cant find them because all the pointers to them have changed it complains. Rebooting of course solves these problems. Regards, Ben
