This problem was caused by the prior commit [1] attempting to fix a much rarer problem (a guru-mode module compi= led for one kernel can sometimes run on a different kernel version if there is = no difference in the ABIs checked by modsymversioning). [1]: https://sourceware.org/git/gitweb.cgi?p=3Dsystemtap.git;a=3Dcommitdiff;h=3D= c8084763b75fe4c8c61a0ddfa69e2d13f04de18e;hp=3D3a29a2eef30f191afbc1bc117b6e5= a2812dfe91b 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. --=20 You are receiving this mail because: You are the assignee for the bug.
