For the record: I'm using mainline kernel v3.14 on a daily basis because of its better support of the MacBookPro.
Same issue is still encountered when using mainline kernels 3.14 and 3.15-rc7

Title:
  [MacBookPro11,2] Suspend delayed because of some timeout issue

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  As requested by penalvch in relation to bug #1323645, here is the bug report for my suspend problem on a MacbookPro 11,2.
  The issue is exactly like as described in #1323645, and concerns the long delay expeirenced when suspending the laptop.
  After starting suspend, the screen goes blank, but the keyboard backlight stays on for about ~20 seconds or more, and only after that the suspend really seems to be happening.
  Wakeup on the other hand is pretty quick, just taking about 2 seconds or so.

  So, expected is a quick suspend (a few seconds at most), but what
  happens is a long delay (20 seconds or more) before suspend is really
  completed.
