I was trying to be concise and polite. Oh well. In any case, here's that output. It seems like GDB thinks that it has symbol resolution but the target just doesn't match. If I weren't certain that I was running the same kernel on the target (as shown by "uname") then I would think that my problem was there. jakeo@jakeo-Ubuntu-Dev:~/src/linux2$ sudo gdb ./vmlinux [sudo] password for jakeo: GNU gdb (Ubuntu 7.7.1-0ubuntu5~14.04.2) 7.7.1 Copyright (C) 2014 Free Software Foundation, Inc.
