I tested the latest upstream kernel v3.19RC3, it did NOT fix the bug.

Title:
  Lenovo Thinkpad Edge E540 suspend/resume failure

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After an update of the Thinkpad Edge E540 BIOS to version v2.16 (J9ET96WW ) the suspend to RAM failes:
   -  general ThinkPad LED (the i's dot) behaved like normal: slowly blinking, which normally means "I'm suspended to RAM."
   - resume was impossible: wakeup failed through mouse clicks, various keyboard keys and combinations and also the power key, only a hard reset (5s or so holding down the power key) could bring it back to life
