You need to install right “kernel-debuginfo” package on RHEL. E.g.:
# rpm -q kernel
kernel-3.10.0-229.el7.x86_64
# uname -r
3.10.0-229.el7.x86_64
# rpm -q kernel-debuginfo
package kernel-debuginfo is not installed
# rpm -ivh kernel-debuginfo-common-x86_64-3.10.0-229.el7.x86_64.rpm
# rpm -ivh kernel-debuginfo-3.10.0-229.el7.x86_64.rpm
# rpm -q kernel-debuginfo
kernel-debuginfo-3.10.0-229.el7.x86_64
If kernel is debug version, you also need to install kernel-debug-debuginfo package:
# uname -r
3.10.0-229.el7.x86_64.debug
# rpm -ivh kernel-debuginfo-common-x86_64-3.10.0-229.el7.x86_64.rpm
# rpm -ivh kernel-debug-debuginfo-3.10.0-229.el7.x86_64.rpm
