Hi all, I just hit the same problem, and I've managed to fix it for my case (Dell E6430 laptop with integrated bluetooth).
I've had exactly the same experience as Till, in that 3.11 caused bt to no longer work after a suspend/resume for me. I'm surprised to hear that the problem has magically gone away for Till, as there is a very real reason causing it in the form of a "fix" in 3.11 . I've written a patch for this (reverting the fix) and send it upstream. I'll also attach it here.

When I suspend the system not only the suspend itself is broken (bug 1213233) but also after waking up I cannot use my Bluetooth devices any more (mouse, keyboard). I have to reboot to get Bluetooth back working. Do not ask me to update the BIOS from 1.52 to 1.57, this leads to bug 1210748.
