Are you loading modules from one kernel build into a different kernel
build?  That is basically saying "the key this module is signed with
isn't in the kernel's keyring".  But that specific key looks like the
one that should be built into the kernel during build, so it should be
there.  Or you're doing what I asked earlier, which would be odd.

Post dmesg output please.
