--- Comment #3 from William Cohen <wcohen at redhat dot com> ---
There looks to be some very hot tracepoints that are only appearing on the
fedora x86 5.0.x kernels that do not appear on rhel7 x86 or aarch64.  Follow
was run for only a short time:

$ sudo stap -ve 'global counts probe kernel.trace("*"){counts[pp()] <<< 1}'
