Title:
  Removing USB WLAN stick during suspend freezes machine

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I have a D-Link DWA 160 USB WLAN adapter, which can be used to freeze
  the machine during suspend. Suspending with the USB adapter attached,
  removing the adapter and then resuming causes the machine to freeze.
  Display comes up showing X correctly but the mouse does not move and
  no keyboard shortcut does anything. I also have the machine hooked to
  ethernet and ping it during suspend. When the machine is up, ping
  works normally. When it is suspended, ping prints nothing. When
  resumed (and the machine is frozen), ping starts printing "Destination
  Host Unreachable".

  WORKAROUND: Suspend & resume without or with the USB adapter attached
  works.
