I have confirmed that the issue is also present in a self-compiled upstream version of v4.9-rc8 and reported it at http://www.spinics.net/lists/linux-bluetooth/msg69063.html

When waking up from hibernation, the chip fails to properly initialize (?). More specifically, when trying to hibernate a second time the notebook will fail to enter hibernation mode due to: "Freezing of tasks failed after 20.00r seconds (1 tasks refusing to freeze, wq_busy=0)" where the task failing to freeze is hciconfig. This seems to be due to a kernel bug initializing the bluetooth device on wakeup from hibernation. The kernel message reads "kernel: Bluetooth: hci0: Setting Intel event mask failed (-16)". I have attached 1) /proc/version_signature 2) sudo lspci -vnvn 3) journalctrl I can confirm that the issue with hibernation is resolved by blacklisting the bluetooth chip in /etc/udev/rules.d/81-bluetooth-hci.rules I have tried the most recent mainline kernel from the ubuntu kernel ppa and can confirm that the problem also occurs there (http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9-rc8/). Please let me know if I can provide any other information to help fixing this bug.
