Hi,

Please can you show the output from:

rpm -qa kernel\*
find /lib/modules -name nvidia*\.ko

What happens if you uninstall (yum erase kmod-nvidia) and yum install 
kmod-nvidia again? Do you see the same error each time? Is it reproducible?

If it's reproducible I suspect it's probably due to weak-modules trying 
to run dracut on the kernel the module was compiled against, which isn't 
installed on your system.
