Did this issue start happening after an update/upgrade? Was there a
kernel version where you were not having this particular problem? This
will help determine if the problem you are seeing is the result of a
regression, and when this regression was introduced. If this is a
regression, we can perform a kernel bisect to identify the commit that
introduced the problem.

Title:
Intel 8265 Bluetooth ([8087:0A2B]) fails to init properly on wakeup
from hibernation
Status in linux package in Ubuntu:
Triaged
Bug description:
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.
