Title:
  [LENOVO 20B7S1GD00] suspend/resume failure

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Resuming from suspend yielded a black screen. Trying to drop to
  another tty didn't help. I suspect this may have something to do with
  bcache or efi.

  This is on a ~5 month old Lenovo T440 with Ubuntu 14.10. I had no
  problems resuming from suspend with 14.04, but that setup avoided
  using bcache or efi.
