Kernel:/stable:/Backport/standard tracks stable for 15.2 users
Kernel:HEAD:Backport appears to track mainline for 15.3 users
Both should be updated to 15.3 now.
There was a change in the kmod() dependencies between 15.2 an 15.3 so the 15.2 kernel does not work for 15.3. It may work the other way around but there was a glibc update so the -devel packages probably won't work on 15.2
