This is expected.  You turned off an expert option, disabling
emulation of a deprecated feature that your init needs. :)  If you
enable that option but boot with vsyscall=none, you'll get the same
OOPS, but you'll get a helpful error message, too.

Either force CONFIG_X86_VSYSCALL_EMULATION=y or upgrade to a modern
gilbc and make sure you rebuild all your static binaries.
