You've configured with: CONFIG_LEGACY_VSYSCALL_NONE=y which is not valid when you're running binaries that are compiled with as old a glibc as you're using. *Dynamic* glibc binaries have been fine for a long time, but static glibc binaried (e.g. your init, I presume) need a glibc that's only a couple years old. You could fix it by either disallowing that particular configuration or by updating your distro. --Andy
