CentOS virt - Dec 2015 - How to debug kernel with kernel-3.10.68-11.el6

Hi all


I used kernel-3.10.68-11.el6 as dom0 and config kdump



I have got vmcore file when compute crash, but not found debuginfo package from
http://debuginfo.centos.org/



I found  kernel-3.10.68-11.el6 set CONFIG_DEBUG_INFO=n



Why not set this key?  Is there any other method to debug when compute crash


Best
