Sounds like you've removed something you shouldn't have.
Copy GENERIC to your own file, and the MAXMEM line and
build that (without changing anything). If that doesn't
work, you've got a memory problem. If it does, add each
of the other mods one at a time and test each kernel 'till
you find out what broke things.
