Title:
  [reiserfs] Suspend/resume corrupts external data storage devices

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  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.
