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. I am running Maui Linux, which is basically Ubuntu 16.04 but includes more up-to-date KDE packages. --- ApportVersion: 2.20.1-0ubuntu2.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: leonard 1336 F.... pulseaudio CurrentDesktop: KDE DistroRelease: Maui 2.1 InstallationDate: Installed on 2016-12-02 (5 days ago) InstallationMedia: Maui - Release amd64 (20160811) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 8087:0a2b Intel Corp.
