Hi Frank,
I run stap-report and the only thing that seems out of place to me is
the Build ID diff between the kernel and debug-kernel.
== (eu-readelf -n /boot/vmlinuz-3.10.0-514.26.2.el7.x86_64 || readelf
-n /boot/vmlinuz-3.10.0-514.26.2.el7.x86_64) | grep Build ==
Build ID: 62b54b1aac6eeaa4cd469439011f8a97558400e0
== (eu-readelf -n
/usr/lib/debug/lib/modules/3.10.0-514.26.2.el7.x86_64/vmlinux ||
readelf -n /usr/lib/debug/lib/modules/3.10.0-514.26.2.el7.x86_64/vmlinux)
| grep Build ==
Build ID: 9812ec6054800f5f9ee0e65ad9c780c8273200c3
