You probably removed npx0 (see npx(4)) from your kernel configuration file because you do not have a math co-processor. The npx0 device is MANDATORY. Somewhere inside your hardware lies a device that provides hardware floating-point support, even if it is no longer a separate device as used in the good old 386 days. You must include the npx0 device. Even if you manage to build a kernel without npx0 support, it will not boot anyway.
