Very good point! I'd clear the /usr/src/obj directory as pointed out, then build a generic kenel, install it and boot from it. Then you know you've got a working kernel to fall back on. At that point rebuild your custom kernel with correct commands as pointed out in the previous response by Michael; i.e. `make buildkernel KERNCONF=MYKERNEL` ... etc.
