The ELRepo Project has regularly released a kernel-lt (long term supported)
package set for both enterprise Linux 5 & 6. These kernels have been based
on the linux-3.0.X stable branch.
The linux-3.0.X stable branch will be reaching end of life this coming
October  and a decision will have to be made with regards to the
future of the kernel-lt package sets that we provide.
There are a number of options available, the most radical being to stop
building and providing such kernel-lt package sets. However no decision
has yet been made.
A thread has been started on the ELRepo users' mailing list  where
subscribers have been asked to assist the Project's administrators in
making a decision.
If you would like to be part of the decision making process, please
contribute to that mailing list thread.
