Exactly. I was asking about this few weeks ago. When the kernel-firmware 
package lags behind the kernel update, then dracut prints this warning. Me 
and Dave Jones voted for those warning to go under debug option only (see 
thread "dracut speed and kernel version"). Seems it is either in the 
queue, forgoten or Harald decided to not put them under debug.
