[Bug runtime/9927] 2.6.29-rc7 - kernel crash with sharedbuf.exp stap test script


------- Additional Comments From mhiramat at redhat dot com  2009-03-12 15:58 -------
$ eu-addr2line -e vmlinux 0xc045b3cb
/home/mhiramat/ksrc/linux-2.6/kernel/module.c:2298

2292  free_core:
2293         module_free(mod, mod->module_core);
2294  free_percpu:
2295         if (percpu)
2296                 percpu_modfree(percpu);
2297 #if defined(CONFIG_MODULE_UNLOAD) && defined(CONFIG_SMP)
2298         percpu_modfree(mod->refptr);
2299 #endif
2300  free_mod:
2301         kfree(args);

it seems mod->refptr is invalid.

Perhaps, below commit caused this issue.
