  ThinkPad X1 Carbon 3rd(2015 version) fails to suspend from the second

Status in linux package in Ubuntu:

Bug description:
  version: 3rd(2015 version) on Trusty(14.04)

  It suspends and resumes successfully at the first time, then WWAN
  devices disappear and fails to suspend.

  workaround 0:
  BIOS, Always On USB to disable, USB 3.0 mode to enable

  workaround 1:
  disable cdc* modules in rootfs and initramfs(you will lose WWAN feature)

  workaround 2:
  reset that WWAN device from xHCI(USB 3.0) port to EHCI(USB 2.0)

  We still need a fix.
