Actually I take it back. It looks like the new locore.o was not
combined properly into the kernel image. I removed all object files and
rebuilt from scratch and no longer can reproduce the SEGV crash.

I do see other crashes when booting into multi-user mode, so looks like
some issues still remain. Can you remember any other relevant fixes you
made apart from locore.s? I can try and backport those to 11 until the
interrupt issue is resolved in -current.
