--- Comment #4 from William Cohen <wcohen at redhat dot com> ---
I have a specific f39 x86_64 machine that seems to encounter a similar problem
with the poll_map.exp test both running on the bare hardware and on a guest VM.
 poll_map.exp times out and the dmesg output has:

[ 4631.997499] kprobes: kprobe jump-optimization is disabled. All kprobes are
based on software breakpoint.
