Well, you made some change that wasn't correct, and the kernel doesn' like you. To fix: 1) At the boot: prompt type 'unload' then 'boot kernel.GENERIC' to get your old system back. 2) Double-check your changes ('diff -u GENERIC mykernel' works great for this) Edit as necessary. 3) Rebuild an reboot.
