Public bug reported:
Ubuntu will permit suspend/resume (have not tried hibernate) without
attempting to unmount any external USB storage devices, even though
processes may still have open files on these devices. After the system
is resumed, the USB storage devices may not be present, due to not
having been re-enumerated yet. This can and DOES result in data
corruption on the filesystem on the external device, as evidenced by
errors in dmesg and having to do journal replays. I am not sure that the
dmesg here will have the whole story (due to dmesg -c having been run as
part of another bug report) but the parts that may not be there
basically boil down to reiserfs being very unhappy that the block device
was yanked out from under it.
As a policy decision, it is WRONG to allow suspend to take place unless
externally-attached USB block devices are still mounted. The system
needs to attempt to unmount everything in /media prior to suspending,
and needs to FAIL TO SUSPEND (throwing an error) if all devices cannot
be unmounted due to some of the mount points being in use.
