Thanks. I guess that makes sense. But I still have no idea how to obtain the 
sources to build. I would backtrack to a previous one (193.13.2), but that one is 
missing kernel-modules-extra rpm package, even though koji[1] shows it was built.
This is the first time I saw an actual binary rpm missing, which is worrying.

So I have backtrack two levels, to 193.6.3.

Any idea when we can expect release of 193.14.3?
