You can edit the Makefile and append something to the EXTRAVERSION. Then, after applying the patch, check for rejects like this: $ find -name \*rej If you get no output, go ahead and compile the kernel, install it, and reboot. Then run: $ uname -r If it shows the string you appended to EXTRAVERSION, you are indeed running the patched kernel. Lee
