    and quite often the user has unloaded / loaded modules in the meantime
    and the oops is useless.

    It would be nice if klogd's oops detection just passed everything to ksymoops
    untouched, and stored everything somewhere using -m

    I don't see any reason why the internal profiler can't have an extended EIP
    range to catch module samples either. Perhaps I'm missing something. Perhaps
    no one cares enough ...
