I assume you mean 'make installkernel' there.

At this point, I think you first have to reboot to your previous
kernel.  To do that, reboot again.  Press the space bar (or
something other than enter) so you get into the boot-loader.
If you have the newer boot-screen, there is a menu option
which will get you into the boot loader.

Once you are in the boot-loader, type:
     unload
     load /boot/kernel.old/kernel
     boot

That should get you up on the old kernel.  Assuming that works,
the first thing you should do is:
     cd /boot
     mv kernel kernel-BAD
     mv kernel.old kernel
