Public bug reported: I am experiencing issues with hibernation on a xiaomi mibook air with the Intel 8265 Bluetooth chip ([8087:0A2B]). 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. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Attachment added: "logs.tar.gz" https://bugs.launchpad.net/bugs/1648526/+attachment/4789078/+files/logs.tar.gz -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1648526 Title: Intel 8265 Bluetooth ([8087:0A2B]) fails to init properly on wakeup from hibernation Status in linux package in Ubuntu: New Bug description: I am experiencing issues with hibernation on a xiaomi mibook air with the Intel 8265 Bluetooth chip ([8087:0A2B]).
