Please note that I have manually installed the yakkety kernel from the kernel ppa in an attempt to fix the problem. The above logfiles where generated on the yakkety kernel. The problem also occurs with the 16.04 "default" kernel version.

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.
