Title:
  Suspend Failure on Thinkpad E540 20C6CTO1WW

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  The laptop failed to suspend, screen went black but the fan stayed on.
  Resume was not possible.

  This is probably the same issue as
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1331077 but since
  my hardware seems slightly different this is a new report.

  The issue seems somehow related to usb 3 support, with usb 3 disabled
  in the bios suspend and resume works.

  The suspend problem still occurs with mainline kernel-3.16-rc4, let me
  know if you need logs from any other kernel version.
