Subject: [Bug 25832] kernel crashes upon resume if usb devices are removed
 when suspended

https://bugzilla.kernel.org/show_bug.cgi?id=25832

It's a *lot* harder to repeat it with just one drive attached. Over 20
suspend/resume cycles I only managed to repeat the freeze once with a single
drive attached (with the 500GB drive attached in this case).

I doubt very much that a particular program is accessing the external
partitions. In my testing I just allow Gnome to mount the partitions and once
it has settled I run the sleep command. A "lsof|grep media" after the
partitions are mounted doesn't show anything accessing the external file
systems.

Is it relevant that when I start the suspend cycle but before suspend occurs
there are some kernel messages saying that the external partitions are being
remounted? I would have thought that they would be unmounted without a remount
before suspend.
