Sorry. But this the first failed kernel in some 40+ years. So I'm now second guessing every move I make... So if I break to the boot prompt and choose boot kernel.old followed by cd /usr/src, make buildkernel KERNCONF=<my-kernel>, make reinstallkernel KERNCONF=<my-kernel> boot -s installworld dance. I'm good to go? Thanks! I really appreciate all the hand holding here.
