Hi Yasha--I ran a set of the 3.10 elrepo kernels on top of SL6, and that mostly works OK. You do see a few things at the perimeter
that break, for instance the utilities that govern cpu speed, and in general the structure of the /proc file system changes so anything that depends on that may be confused. You can also have confusion if you have kernel-specific firmware rams and you have to be sure you do it right. I have not tried any of this in SLF7 yet. In SLF6 the minor version upgrades didn't clobber the elrepo kernels because they were actually a different rpm name.

For ELRepo, there is an EL7 community kernel repository. Is anyone using this for production machines (presumably, yes)? If so, how do these differ from the "stock" SL (CentOS, RHEL, ...) kernels? If one uses an ELRepo kernel, and one then does a minor release upgrade of SL (assuming yum upgrade or something similar actually works, not requiring smashing the system partitions), will the ELRepo kernel "parts" play nicely with such a SL upgrade, or are there conflicts resulting in either no-boot (system failure) or instabilities? For "new" laptops/tablets that do not have the necessary drivers in stock SL, does the ELRepo kernel repository provide additional current drivers (as might be present in Ubuntu or even fully enthusiast, not enterprise production, Linux distros)?
