I too have had the same issue...


Notebook: Dell XPS 13 9360
bios: tested with 2.9.1 and 2.10.0
OS: Debian stretch 9.8 
Kernel: 4.9.0-8 debian 4.9.144-3
Wi-Fi/BT module: Intel Dual Band wirelss AC 8265, rev=0x230
Firmware: iwlwifi-8265-22.ucode
BlueZ: 5.43-2+deb9u1
BT Mouse: Logitech MX anywhere 2s

------

When attempting to pair one of 4 things will happen:

1. the bluetooth module locks up and stops responding - time out messages are
seen in dmesg

2. The wifi will reset but will return to a normal state with a failed
bluetooth as above

3. wifi and bluetooth will disappear and stop responding but wifi is
recoverable by invoking rfkill via the wifi hot key ( fn f12 )

4. The entire device stops responding and shortly after the machine will freeze
- there may be a panic but i can't see it due to lock up ( nothing written to
logs )

The pairing process will not complete as the device stops responding before
then.

Resetting the pci device via the /sys interface results in an instant hang

Other two xps devices i have contain ath10k cards and dont seem affected, mouse
can also be paired to an android device without issue.

tried bios upgrade to no avail. attempted using firmware direct from
linux-firmware repsitory instead of firmware-iwlwifi package ( 20161130-4 ) no 
change

only fix i've found for this was to add the bt_coex_active=0 option when
loading the module ( modprobe: options iwlwifi bt_coex_active=0 )

this allows a connection to occur and for the device to pair however the mouse
movement on screen seems to be quite jittery at times.

Do you folks use gnome-control-center to pair?

Take a look at [1] if gnome-control-center is used:

I certainly did use gnome-control-center.
I've just tried again with Fedora 29 (gnome-control-center-3.30.3-1.fc29.x86_64
+ bluez-5.50-3.fc29.x86_64) and out of five remove, add, force reconnect) I
only received a single failure.
/usr/share/gnome-bluetooth/pin-code-database.xml does not seem to have any
tweak applying to this mouse.

I tried the pairing via the gnome control center, command line ( bluetoothctl )
and via blueman. These were done while in a gnome session however

All three attempts failed as above.

My intention is to ask you to try adding this entry to pin-code-database.xml:
<device vendor="logitech far east" type="mouse" pin="0000"/>

It seems like the bug has been fixed in bluez 5.50-6. My Logitech M336 works
now.
