--- Comment #6 from Serhei Makarov <me at serhei dot io> ---
Thanks for providing the detailed info. This problem was caused by the prior
commit [1] attempting to fix a much rarer problem (a guru-mode module compiled
for one kernel can sometimes run on a different kernel version if there is no
difference in the ABIs checked by modsymversioning).

For now I reverted the commit in SystemTap git master since it clearly had
undesirable results. I'll use your info to reproduce the problem for myself and
see if there's a better way to fix it that works across all the different
configs. Keeping the PR open to track that work.
