RHEL6 042stab079.4 contains a critical bug in loadavg vs checkpointing 
(#2699)
and therefore is pulled off from yum repository for now.

If you have updated the kernel and not yet rebooted, please remove this 
kernel.
If you are currently using it, please note loadavg values for containers 
are broken.

A fixed kernel (079.5) is being worked on, ETA is next Monday.
