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.

Thanks,
