Nan,

The kernel running on your system is kernel-debug-3.10.0-123.el7.x86_64

[root at localhost ktap]# uname -r
3.10.0-123.el7.x86_64.debug
                        ^
                        '....

It is provided by kernel-debug-3.10.0-123.el7.x86_64.rpm

The kernel-debuginfo package installed on your system is for normal kernel.

[root at localhost ktap]# rpm -q kernel-debuginfo
kernel-debuginfo-3.10.0-123.el7.x86_64

To fix it, you need to install
kernel-debug-debuginfo-3.10.0-123.el7.x86_64.rpm
