I have the same problem. Anybody can solve this problem?

I have installed kernel-debuginfo packages.

[root@localhost openresty-systemtap-toolkit]# rpm -qa|grep ^kernel kernel-3.10.0-327.el7.x86_64 kernel-debuginfo-common-x86_64-3.10.0-514.16.1.el7.x86_64 kernel-tools-libs-3.10.0-514.16.1.el7.x86_64 kernel-headers-3.10.0-514.16.1.el7.x86_64 kernel-tools-3.10.0-514.16.1.el7.x86_64 kernel-devel-3.10.0-514.16.1.el7.x86_64 kernel-devel-3.10.0-514.2.2.el7.x86_64 kernel-debuginfo-3.10.0-514.16.1.el7.x86_64 kernel-devel-3.10.0-327.el7.x86_64 kernel-devel-3.10.0-862.9.1.el7.x86_64 kernel-3.10.0-514.16.1.el7.x86_64
