This patch titled "kobject: remove the static array for the name" looks like it's responsible. Reverting it cures the problem. The root of the problem seems to be, that decl_subsys() initializes k_name with a string constant. Then subsystem_unregister() will put the kobject, which will free the k_name. So, what's the right way to deal with this?
