Just checked in the following git commit. Check to see if this addresses some of the problem. There might still be other -g use with wild= card probes that cause problems. commit eb760b0d09d8170988add7f2052ff6e40a747304 (HEAD -> master, origin/mas= ter, origin/HEAD) Author: William Cohen Date: Wed Mar 20 10:24:53 2024 -0400 Remove unneeded guru mode option from poll_map.exp Guru mode should only be used when it is really needed to allow the systemtap script change program state or disable some safety check or black list exclusions. With guru mode enabled on a particular machine this test would attempt to probe kernel.function("vfs_caches_init").call, an initialization function on a page that would would later freed. The script would get page fault when attempting to install the kprobe for this function. --=20 You are receiving this mail because: You are the assignee for the bug.=
