    Note that the respective update changed /etc/conf.d/alsasound (a local
    configuration file) to include
    UNLOAD_ON_STOP="no"
    KILLPROC_ON_STOP="no"
    This change by update is not activated by a mere emerge; one needs to
    incorporate that change with dispatch-conf or an equivalent method.
    (Or simply edit the file to have these variables set to "no".)

    Is it a kernel issue if a script attempts to unload a busy module, then
    fails to proceed? I wouldn't think so.

    But more importantly, is this init scripts related bug really what's
    happening at your system? Or do you actually experience an entirely
    different bug?
