[CentOS] elrepo kmod-nvidia issue with update

when I do yum update, elrepo offers kmod-nvifdia, but yum does this:

--> Processing Dependency: kernel(sme_me_mask) = 0x17fbce60 for package: kmod-nvidia-390.48-2.el7_5.elrepo.x86_64 --> Processing Dependency: kernel(reservation_object_add_excl_fence) = 0xea98efc0 for package: kmod-nvidia-390.48-2.el7_5.elrepo.x86_64 --> Processing Dependency: kernel(drm_vblank_init) = 0xdcd50a49 for package: kmod-nvidia-390.48-2.el7_5.elrepo.x86_64

.

.

.

repeatedly, then says:

You could try using --skip-broken to work around the problem  You could try running: rpm -Va --nofiles --nodigest

Is there a problem on my end or theirs?
