Hi Dave, I have found that crash-4.0.9 cannot load any extensions on 32-bit hosts, even echo.so. Running crash with -d5 on a live 32-bit kernel I can see that it fails as crash> extend extensions/echo.so extend: ./extensions/echo.so: machine type mismatch: 3 extend: ./extensions/echo.so: not an ELF format object file if (!is_shared_object(ext->filename)) { error(INFO, "%s: not an ELF format object file\n", Something is wrong in is_shared_object() logic on IA32. It is interesting that there are no problems with crash-4.0.9 and extensions on 64-bit systems. As most of us are running 64 bits, this probably explains why nobody reported this bug yet.
