  Suspend issue with Dell Venue 11 Pro 7140

Status in Linux:
Status in linux package in Ubuntu:

Bug description:
  Instead of suspending the machine into a state where it can be started
  quickly, it appears that suspend causes the system to end up in a
  state which requires a forced start.  The power light is off, and the
  only way to start the machine again is to hold down the power button
  for more than 5 seconds. A quick check of uptime shows that it did,
  indeed, start again.

  I'm attaching a suspend log.
