To make that oops even remotely useful, you do need at least CONFIG_DEBUG_BUGVERBOSE enabled, and really preferably also CONFIG_KALLSYMS. Otherwise there is no symbolic debug info, and it's impossible to even really guess what is going on. It seems to happen early on module load (which is good, that makes it likely easier to debug), but without knowing the function and call chain, it's a bit useless.
