I'm not that familiar on this subject, but I think it's an unfortunate
necessity of yum's design.

You're effectively telling it to upgrade a module.  But the new version of
the module requires a new kernel.  If the new kernel can't be installed
for any reason, that implies that the module has failed to upgrade, which
is an error.
