Comment 35 for bug 1073433

Does anyone else see two lines about 'hub_port_status failed error (-110)' just before shutdown and immediately following 'mount: / is busy'? These errors always occur on several computers using different filesystems. (None of the workarounds mentioned above or in bug #1061639 resolve the problem of fsck/log replay on next boot.)

Is there a way to kill all usb processes before shutdown to try and determine if the usb system is interfering with the clean unmount of the filesystem?

I'm using kernel 3.5.0-23-generic #35-Ubuntu SMP Thu Jan 24 13:05:29 UTC 2013 i686 i686 i686 GNU/Linux

This may need a separate bug report, if the usb system is a possible cause and other filesystems also run fsck/log replay.
