    Please provide info about:
    * automounter startup options
    * automounter configuration file(s)
    * client/server kernel version and .config
    * ksymoopsed SysRq-T dump of a couple of hung processes
    (no, not all processes! please select 2-5 hung processes _only_
    before feeding dump to ksymoops :-)
