It also uses strcmp directly. And it also calls modlist_lookup2 that in turn calls modlist_lookup . It can also recurse back out to linker_load_module. It appears that getting a dump during the initial general protection fault and getting it savecore'd and crashinfo'd so that we can see a kgdb backtrace is what would be the primary next-useful-thing. I also hope that: static modlisthead_t found_modules; can be examined to see if the modlist has any bad name pointers that strcmp ends up trying to use. --=20 You are receiving this mail because: You are the assignee for the bug.=
