The hardened-patches contains the following: 4423_grsec-remove-protected-paths.patch 4420_grsecurity-2.2.1-2.6.36.2-201012121726.patch 4435_grsec-kconfig-gentoo.patch 4421_grsec-remove-localversion-grsec.patch 4425_grsec-pax-without-grsec.patch 4430_grsec-kconfig-default-gids.patch 4422_grsec-mute-warnings.patch I do have UDEREF enabled: # grep UDEREF .config CONFIG_PAX_MEMORY_UDEREF=y I can try disabling it when I'd be willing to drive to work and reboot the thing.
