The kernel module signature verification has been enabled for your system, which is giving warnings while loading modules that has not signed by the vendor. Not a big problem though... Try to compile with the following flags off during menuconfig: - CONFIG_MODULE_SIG - CONFIG_MODULE_SIG_ALL Hope it helps.
