--- Comment #5 from William Cohen <wcohen at redhat dot com> ---
On the machine that observed the problem poll_map.exp is using -g to compile
poll_map.stp. poll_map.stp uses 'kernel.function("vfs_*").call' insert kprobes.
With -g mode one of the probe points it attempts to instrument is
'kernel.function("vfs_caches_init").call'.  This is an initialization function
on a page that is freed up after initialization.  This problem appears to occur
on one particular machine.  I suspect that it might happening on other machines
for other for tests/functions.  It might be helpful to look to see if anything
in /proc/kallsyms match up with the lower 24-bits of ffffffffa64a65c0 (4a65c0)
on the machine that the problem initially occurred on:

sudo cat /proc/kallsyms |grep 4a65c0

Then take a look to see if any of those functions have and __init in front of
the of them using the function lookup on
https://elixir.bootlin.com/linux/v6.8.1/source.
